After a good night's sleep, here are my thoughts regarding our trip.
1) It is a long way from Kentucky to Wyoming! We stayed two nights at Custer, two in Cody, four in Yellowstone, and two in the Tetons. In hindsight, given the same number of days, I would probably trade-off a day in Yellowstone for an extra one in the Tetons. The Tetons are less crowded, and the scenery is outstanding.
2) We liked staying in cabins better than hotels. We stayed in a small cabin at Custer and it was cozy and secluded. Also stayed in a very nice cabin at Signal Mountain in the Tetons.
3) We liked the Tower/Canyon area of Yellowstone the best. Least favorite area of Yellowstone was around the lake and east entrance.
4) My 400 5.6 lens was plenty long enough for about all of my wildlife shots. In fact, sometimes it was too long, and I would have to switch to my 70-200 for the shot. I would think a 100-400 zoom would be ideal for the park. The only animals that were clearly out of range of 400 mm were the wolves. They were just too far away, but it was awesome to see them.
5) I am generally happy with my wildlife shots, except my grizzly pics. I had two golden opportunities of a mama grizzly with her cubs, but my pics turned out a little soft. And of course, the best poses were the softest! I think I was just too pumped when I was taking the pics of the grizzlies, and used poor technique. I should have slowed down, used my monopod, and watched my settings better.
6) A "photography" vacation can be exhausting! Getting up at the crack of dawn and staying out till dusk is tough on a middle-aged man. I was able to get a nap on some of the days, which helped.
7) We were able to ride the motorcycle on the Needles Highway, Iron Mountain, Chief Joseph, and Beartooth. All were great rides, but the Beartooths were the best.
All in all, it was an awesome vacation and I'm so glad we had the chance to go. I'll be happy to answer any specific questions about our trip. I'll start posting some pics now. Feel free to comment and critique them.
