I was there 3-4 yrs ago - two years before the big flood there... stayed at the Hatchet Resort near Grand Teton and Pahaska Tepee Resort east of Yellowstone. Also stayed at a hotel in Cody and Sheridan visiting Big Horn, the Old Coral Hotel & Steak House near Medicine Bow-Routt and finally in Casper before heading back home.
Bit and beautiful places... but I heard the winters are brutal there. Actually, I went there during Memorial weekend and it was still snowing in Yellowstone that year.
