Swapped the bike for my skis.
I've wanted to try this for years - and finally pulled the trigger. We've had almost two feet of new snow in the past several days, so I thought it would be cool to ski in to work. The only problems: my skis are pretty crappy, I'm a pretty crappy skier, and my route is pretty crappy. It took my about an hour and a half to ski the 5 miles to work. I was either on plowed bike path/road (sometimes plowed down to asphalt... with some sand/gravel thrown in) or breaking trail through 2 feet of snow (exhausting). I didn't wear double socks, and I ended up getting really bad blisters on the backs of both feet. I also plunged knee-deep in an ice-cold stream near the end of my trip. At least that made my blisters feel better. Anyway, it was cool to try it once - but I think that a bike is the best vehicle for my commute!
