I'd agree about camping in Wyoming from about Memorial Day through September and sometimes into October but from November through January, February, March and most of April? It akin to what a friend said that lives in Pinedale, WY. He'd been there for a few years when I asked him how he liked the area. He said, "Well, part of the year, it's good snow mobiling and the rest of the year, it's pretty poor snow mobiling. Nuff said.
