You read it first here, so it must be true. No need to check snopes though, the American Alpine Institute is already on the case, saying: Somebody apparently didn't do their homework [no shit sherlock]. There clearly isn't a naked climbing craze in the United States. [boo hiss] However, a calendar that features black and white images of climbers in the buff entitled Stone Nudes has been around for years.
I suppose that's an improvement on the WI ;o)
