Personally, I don't see how a flimsy rod attracting lightening would be good for the house. I saw a long, ranch-style house hit by lightening in the center, and the whole middle of the house was gone.The power is too great to ground it that way through a mere wire. On tall buildings, though, the rods connect to the steel superstructure and they have been photographed grounding the lightening perfectly. When I was a child, we saw in our social studies book a photo of lightening hitting the Empire State Building with no harm done. It was taken at night with shutter open on B setting during a storm. Now such pictures are common.

Airplanes are another matter and it is a mystery to me how they survive regular lightening hits. In 1967, an airliner exploded when lightening hit the fuel tank, so they adopted methods of keeping the lightening on the outside aluminum skin--when charged, the plane is the source of a lightening bolt rather than the target. Of course, most of the flights are above the storms.

You're right Charles, it wouldn't absorb a direct lightning strike. That's not the point. It grounds the ions before the strike occurs at that location. Mine have been on this house for probably 100 years. They've been around since Ben Franklin. I also wonder about the surrounding topography. A farmhouse on the open plains might be the tallest target around for miles. 100 years ago, my house would have been on open land. Now I'm surrounded by 60-foot maple trees. And thunder and lightning storms are common around here.

They work, but they have to be hooked up right. When I replaced the roof with metal, on my 1880 farmhouse, I took the set of three with the cable harness down and laid them on the lawn. They are connected in series with a copper cable. The cable runs the length of the roof and down each end to a buried ground rod. I set them back up with the cable all connected when the roof was finished. Lightning occurs with an overabundance or imbalance of positive and negative ions in the atmosphere (I may be corrected on that). The purpose of the lightning rod hook-up is to bring that charge near the house to ground before a discharge or lightning strike occurs. It protects the immediate vicinity of the house. Lightning does not actually strike the lightning rod if it is properly grounded. The glass balls you sometime see are just for decoration. I have mine and they have turned lavender from sunlight exposure over the years. Sorry for a pedantic explanation, but I'm kind of enthused about this old technology. :)

That's terrific! I think drones are one of those unexpected events in the evolution of technology that will change the way we do a lot of things. Like lasers, PCs, cell phones and digital photography.

That's funny, but racoons don't get guilty, they're aggressive opportunists, he was probably PO'd about getting caught. Great shot!

We can see it's a plane, I like the wide open fields, clouds on the horizon, blue yonder sky and sun. Top photo preferred. it's still a good catch.

Not a perjorative. I see there actually is a Girlie Girl brand of accessories aimed at young ladies of a certain age. Consider American Girl dolls that are hugely popular even with mature women.

Nice set. That's a big sport here on Lake Champlain.

I agree, especially going manual when I want to check on exposures and focus.
