There's always skiing.....that's what I do. I find that mountain biking is great crossover training for ski season. Hey, it gets you out into the fresh air. And if you don't like alpine, there is backcountry skiing, or classic nordic, skate skiing or even snow shoeing.... all great workouts.
Why stay inside?

Sometimes becoming a winter sports nut is just a matter of finding the right activity, and then learning how to dress for the elements. Personally I'd go nuts if I had to stay inside in the winter.
