Crested Butte and Telluride

Would it be possible to split a ski vacation between Telluride and Crested Butte? They seem to be about 3 hours apart. We would fly into Montrose and out of Gunnison

Absolutely, yes, we have done this several times although sadly for us not since the 1990s. We would have just rented/returned from Denver and enjoyed the drive. Both wonderful resorts and driving between them scenically spectacular and quite short distances on open roads by the North American measure. Only thing I'd say is get a good 'winterised' car as I recall having to drive over stretches of snow covered roads even on an Easter trip.
