Many good responses. Shooting my two grandson's basketball and a niece's volleyball I went to an 85mm f1.8 prime. I didn't care about getting much beyond my subjects so I didn't need a wide angle lens. The 1.8 gave me the reach and obviously a bit more aperture than my 70-200m f2.8 so I could go with higher shutter speeds.

I have heard a professional photographer friend state several times the most satisfying day of his life was when he decided to drop wedding photography. When I mentioned that during a conversation with another photographer he said for him it would be a toss-up between dropping wedding photography and finally getting rid of his time-share.

When my father was at the last stages of life my siblings and I became interested in the numerous photo albums our parents had. Unfortunately the light bulbs didn't click on until then. Photos going back to 1915 and an interesting era. We discovered that we could not identify many of the people in the photos going back to his childhood, many which were relatives. Between our mother and our dad's first cousin we were able to identify some of the individuals. Due to age and travel distance it was not a quick process. The cousin past away and our mother was in deteriorating health and past on before we were able to satisfactorily cover the mission of photo identification for both parents. My wife and I are now attempting to work on our own collection of photos from our youth on up to present day so our children don't have the same experience. Most of our photos are in shoe boxes rather than albums. I am not as reluctant to toss a photo as my wife is.
Two points: 1) Photos will have limited worth to family members if they have no clue who they are looking at. 2) Inquire if anyone in your family is into genealogy that may have an interest in the albums.

I experienced the problem with 3rd party grips. I purchased ProMaster for both my Canon 6d and 7d and after a few months both had camera connection issues; both hand held and on tripod. The camera shop replaced them (the even cleaned the camera battery contact points) but the second grips had the same reoccurring problems after a bit of time so I don't use them anymore. They seemed to fail connection at the time I had a terrific shot in the lens. I will say the grips helped me with handling the camera and extended battery power but have survived without the grips.

The replies to my Focus Peaking inquiry have been extremely educational and informative. I think many of us look for reasons to upgrade but the input has caused me to backup a bit and reconsider the cost of a camera upgrade solely for the purpose to acquire the focus peaking feature. I do not have any manual only lenses and none of my Canon or Tamron lenses are compatible with mirrorless so not looking to go in that direction. I tend to use 10X magnification a lot off a tripod and am comfortable with the results so focus peaking may not be that useful to me. The big take-away from the input is that I need to rent models with the feature and experience how the feature performs with each model. I have found that the people at my camera store have very limited experience with the feature. To those who provided input - thanks much.

Good point! Thanks

I have been exploring the "Focus Peaking" feature on some of the newer cameras. One resource promoted the feature as a real asset toward improving an individual's photography. As I read more about the feature it appears to me to be an asset if the photographer was primarily into landscape or architecture photography using manual focus off a tripod. It also appears there is a wide range of how camera models provide focus peaking set-up; such as allowing a custom button to quickly turn it on or off as needed (something not clear in model specification info). Going into the menu could be a hassle. For a photographer not making a living shooting landscape photography I wonder if this feature is that significant. I am interested in experiences with using Focus Peaking.

Being a former city fire chief in Wisconsin I am very familiar with Pierce fire apparatus. Pierce is owned by Oshkosh Trucks, one of the largest manufacturers of military trucks. Pierce apparatus is considered innovative and top quality. One characteristic I noticed about eastern fire departments, they really like to light up their apparatus. The advent of color LED lighting has enhanced that feature demonstrated by your photos. On one visit to the Pierce plant they had just handed off a new truck to a department from New Jersey. I was told the truck had a urinal in it. The engine company the truck was going to was one of the busiest in the US and that truck would seldom be shut-down for more than a few hours a day.

As others stated squirrels are going to be the problem with a feeder mounted on a post. I suggest you consider several types of feeders. Feeders with perches will attract birds such as finches. A flat feeder will attract birds such as cardinals, doves and blue jays. Suet feeders will attract woodpeckers, nut hatches and others. Juncos are ground feeders. My bird feed mix I use in the flat feeder is: 4 parts sunflower hearts and 1 part peanut pieces, with a handful of dried meal worms. From March through May I add a handful of crushed oyster shell. I switched to sunflower hearts to eliminate the mess from the hulls. In the tube feeder I use a finch mix that I also toss some on the ground. I go through a quart of bird seed mix per day in each feeder. Starlings and black birds were a problem when I used cracked corn in the mix so none of that now. Occasionally I will toss a handful of peanuts in the shell in the flat feeder which the blue jays love. During spring through fall I also have several hummingbird feeders and an oriole feeder. During the winter I have 11 species of birds that regularly visit and during migration I will have an additional 7 species that stop. If you are limited to one feeder I would go with a flat feeder. My flat feeder has a shield above it to help keep rain and snow off the seed.
I built an owl nest box and put it in an oak tree in our yard. It took them 3 years to use it but this was the 5th year in a row that a pair of Barred Owls have raised a brood. Four years 2 and one year 1. I probably have two thousand owl photos.

I visited Best Buy to replace a laptop several years ago and the sales guy called over another sales associate who was also a photographer. First question he asked was what I do for post processing and the conversation moved from there. He set me up with a Leveno Legion gamer which he said are better built than the more conventional laptops due to how gamers use them. Two drives (I have the software on one and everything else on the other), fast, great display and a 2-speed fan. Overheating was a problem with my other laptop. It travels with me and has survived several "oops!" that demonstrates it's durability.

Being I am the primary "facilitator" of a local photography club this issue got my interest. I think the issue is one every club should think about regarding being faced with a similar issue, including liability. Our club is established loosely on purpose; don't know if that is good or bad. Thirty-two individuals on the roster with meeting attendance typically 14 to 17. While we have a roster for communication purposes we do not have a formal membership registration or fees. As a club we have formal written "objectives" but nothing else. We have individuals that step-up to provide various assistance when needed, but do not have "officers." We have monthly meetings (prior to covid) with a monthly theme and education component. Because the club participants are male and female we stay away from photo shoots or monthly themes that could be controversial to someone. Individual photographers may use models, but that is on their own composition as they tackle the monthly photo theme. Not being a lawyer, I am confident that facing a similar issue our club has little that someone can grab on to. Always interested in opinions posted to UHH.

Consider contacting some professional photographers in the area. John Gerlach https://www.gerlachnaturephoto.com/ is one that I know of. John live just outside of Yellowstone and knows both parks well. Connecting up with a photographer will likely cost you some money but the knowledge in the area, where to get great photos, camera learning and having a guide will be worth every penny.

Having a pandemic and "senior" moment at the same time I purchased an ATV. Admittingly, an ATV is not the greatest for close-up wildlife photos, but having issues walking more than a couple of blocks it gets me out and about with nature. Primarily landscape photos and wildlife from a distance. Needing storage on the ATV to carry my camera gear I spent a lot of time exploring what is out there. I purchased a Moose Utility Division rear rack bag that works great: https://www.mooseutilities.com/products/?productId=461727 The rear long bag handles both my monopod and tripod along with a small beverage cooler. Each of the two side bags store a camera (full frame and crop) and lenses. They are double closed with a zippered flap and a button flap to keep dust out.
There are webbed sleeves on each side for holding an item such as a bottle of water but dust makes them useless for most items.
The rack bag worked well strapped on a friends boat as well.

Thanks much to all who responded - very informative responses. I have a much better idea of where the ExpoDisc might be of benefit and where the expectations may be disappointing. Prior to submitting my inquiry via UHH I did watch the promotional videos on the ExpoDisc web site. While spending $50 on a camera accessory is not a huge outlay, I felt I needed input from experienced photographers not being paid to say something. UHH again proved to be a valuable feedback resource.
