Im heading down to Cody to pick a new truck next weekend and I'm looking for something fun or interesting to do for a day while i'm off work and in the area, or near Billings
the Buffalo Bill museum, can't miss it as it is pretty much the center of town and about all there is in town. Also you can head west out of town and see the dam, power plant, and reservoir. If you head south out of town you can go down to Thermoplis and see the tar pits and dinosaur bones. The museum is a good way to kill a day though, just watch out for the tourists from Canada. When I was there 2 years ago the french speaking Canadians were packed in there and the rudest people of any I've ever encountered.
