Monday through Friday is the best time to head to the hills, for two reasons: Nobody's on the mountain and nobody's on I-70. The folks at Loveland Ski Area know this, which is why they offer a mid-week pass for $249 (or less, if you buy early or are a returning customer). Consider, too, that five-sevenths of the snow falls during the work week and that Loveland sometimes stays open until June. Of course, work can't be your priority if you're a mid-week skier or boarder. But maybe it shouldn't be.
