CRESTED BUTTE — Rumor had it that in the not-too-distant past, folks at Crested Butte Mountain Resort shed their ski togs and bashed bumps in the buff on closing day. A friend assured me such things don’t happen anymore. “It wasn’t a pretty sight,” she claimed. True enough, when my wife and I last hit the slopes of Crested Butte on closing day, nary an Adam nor Eve on skis were to be seen.
