Hello again - yes, this was a fantastic trip! Thanks for the positive comments. One we have been waiting to do for quite some time. You are SO lucky to live close and visit frequently.
The camera boom is simply a hiking pole with a GoPro camera attached at the end with the handlebar/seat post mount. We have two mounted, one mount facing in (for selfies) and the other facing out for those hard to reach shots (high and low). We take it everywhere and get some awesome shots that would be impossible with a regular camera. There are two shots posted - the one out the car and the other of the both of us at grand prismatic pool.
Tips: Summer was fine (and the only time we can go since my wife is a middle school assistant principal), but we made our camping reservation for Yellowstone in February at Bridge Bay campground. If you must go in summer, book early! This was a great campground with a central location so we were able to go all over the park. If you reserve there, ask for Loops G or H so you can have a more secluded/woodsy site. We did not have reservations in Grand Tetons, but were able to get a site with no problem at Lizard Creek campground. This was the northern most campground and pretty awesome if you ask me. They don't take reservations - but just get there early.
Take your time! We were in Tetons for 4 days, Yellowstone for 5 days, and took a detour on our way home to Cody to go to a rodeo and visit the Buffalo Bill Museum. If you can squeeze that in too it was worth the extra miles.
Other tips - binoculars are a must! Get up early and leave just before sunrise to see the most spectacular scene around the mud pots...cooler weather = more steam = a mystical scene. Then head up to Lamar valley to see critters. That was when we saw both a grizzly and black bear. But the moose and wolves were still elusive. Talk to the die hard animal watchers. They will give you amazing viewing tips.
If you fancy going to dinner - do not waste your money on eating at the yellowstone inn. It was not worth it and you will eat better at your campsite (just my opinion).
Oh - and the generator rocked! We we able to keep the a-frame battery charged, all camera equipment charged, and watch a movie when it stormed at night. :-)(Campgrounds have generator hours and tent only loops so you don't upset the non-gen crowd.)
