You will love GT and YNP. They are awesome and photo opportunities are uncountable. If possible, I suggest spending at least twice as long as you have planned. Our first time there in 2014 we were almost overwhelmed and felt as if we had too little time.

I recommend buying a guidebook (There are plenty) ahead of time and studying it. Prior to our trip I bought "Compass American Guides: Yellowstone and Grand Teton National Parks (Full-color Travel Guide)" and it was very helpful. We referred to the guidebook many times before our trip (and during) and had general knowledge about the various features when we arrived. Without a guidebook and some research online we would have been completely overwhelmed.

I regret being physically unable to hike up the hill to look down at the Grand Prismatic Spring. I believe that would be a fantastic view and photo op. One of my main wishes was to see wolves and our guidebook directed me to the right place at the right time. We plan to return to GT and YNP this fall or next spring.

I had wanted a Canon S95 and when the S100 was introduced I wanted that even more. I hesitated as I already had four digital cameras. When the S110 was introduced in 2012 I was able to buy an S100 at an excellent. I have been completely satisfied with it. When I don't really plan to take photos I don't want the bulk and weight of my D7000 so I carry the S100. It's a true pocket camera. It has full controls and will save RAW images. For nitpickers, it is 1.1 inches thick :-)

If you have a chance to buy a good used S100 I suggest this review: https://www.dpreview.com Ken Rockwell loves the S100 (but he loves almost everything.) I agree with 47Greyfox's disappointment about Canon's direction with this series. When my S100 was stolen from my car I bought a used one in excellent condition.

It's great for candid shots where an SLR may be disruptive.

I agree with SharpShooter. I watched the 1979 Solar Eclipse and the memories are still vivid. I did not get the complete experience because I was busy with my camera. However I did take one of my favorite photos.

I feel fortunate that I'll have a second opportunity to experience this awesome event. I'll be in Depoe Bay OR and one of the first to see this eclipse. This time I'll set the camera for sequential shooting then start and ignore it while I experience the totality.
