Straddling the Wyoming/Colorado border, the place is a massive working ranch -- with bison, camels, llamas, goats and all of your other standard farm animals -- and includes an awesome agritourism component. Visitors can camp or stay in their RVs, or they can rent a room in cabin or bunkhouse, shop at the store, play on the playgrounds, eat at the restaurants, take a train ride, fish, ride horses, etc., etc.
The bunkhouse is cool, but the cabins may be the only "motel" facility in the nation where you can look out over a bison herd from your front porch. Pretty awesome.
One of the most charming parts, however, is the vehicle that the cleaning ladies use to drive from room to room. A beat-up shuttle still painted orange and brown from the 93rd annual National Western Stock Show, which took place in 2000 in Denver.
