Thor, just a couple of things to note: Yellowstone - Make sure you can take a bike into Yellowstone, and you may even have to book to get into the park. I have heard of stories bikes are not allowed, although I have no proof. But for sure I have heard of the park officials regulating the number of tourists into the park.
Second, go see the Anasazi ruins, you won't be disappointed! My .02 Grant Gall
