Wonderful tips. Thank you. We decided to leave Grand Teton and Yellowstone for another trip (maybe US-Canadian trip).

I'm almost afraid of the detailed planning. I haven't gotten even close to the details and I've already discovered (or been pointed to) a million different wonderful sights :)

I'll incorporate all of your tips into the itinerary (they are all very beautiful) and try to come up with a preliminary timeline. There's where I'll really need your help.

p.s. I have a side question. Is it possible to get some sort of canyon fatigue or something like that? I know it sounds silly but this year I've been to Cambodia and after three days of non stop exploration of the Angkor Temples I was almost fed up with them. Don't get me wrong. They are really, really spectacular and one of my favorite places I've visited but they can become a little bit tiring.
