Yeah there's a fiberglass bull which is cool. I never got around to naming him, but I would probably go with something Thai like "Somchai" which means "real man or man of worth", simply because he stands outside all day in the hot sun and never drinks any water. I'm not sure if that's because he's fiberglass or because he's a dedicated employee of the museum but next time you see Somchai, tell him I said hello.
Also the best Thai restaurant in Durango is Sizzling Siam. The rest are imposters.
