There are a million flights between MSP and Denver, are you folks skiers at all? Denver is actually very tame with its winters (you know how it's awesome to hit 40° out in Minnesota a couple times a year? We get up to 65°) and any snow that comes in melts a couple days later. But go on I-70 through the mountains, and you're in ski country. Lots of neat ski towns with great food and, of course, skiing. If you make it out to ASE, they have a bus that runs from the airport to the city of Aspen, which has a ski hill or two within walking distance from the bus stop. I haven't been in that direction, but that bus also goes to Snowmass, CO.

Edit: And in a point of something amusing and possibly useful, the busses have ski racks
