i know everything you need to know about yellowstone. yellowstone is everything the tv makes it out to be and more. plan on walking alot as all attractions are off the road down nice boardwalk paths. if you have the $$ get reservations at oldfaithful inn, its right at oldfaithful, also mammoth hotsprings has a motel, great place to soak off the road. camping is abundant in the park, just use the bear boxes for your food

. it gets cold and has been known to snow at any time of the year up there, so be prepared for cool evenings. if your going to camp, bring a warm bag.
Cody and Jackson are great places to stay outside the park. maybe stay in Cody, do the park for a few days, then ride down to Jackson for a night. about 4-5 days in the area. in Cody there is the buffalo bill historical museum, great museum full of artifacts, art, and more guns than the national guard.
i could type you a book on yellowstone. if you want to know more, let me know.

its an awesome place to visit.
