naw, I prefer biking in winter for similar reasons: don't have to "clear off the bike" or scrape ice, don't have to watch for parking outside puddles, being wet is not miserable when one is a human radiator, biking keeps me warm, I can hear the snow fall, I can feel more sunshine, and I suck less exhaust (I think maybe I just smell it more in winter, but I swear my diesel is stinkier in the snow).
Walking is slow, once I started moving on any wheels (bus, driving, now biking), I pretty much see walking more as a social activity than as a viable transportation method (for me personally, others use it and I respect that, it's just not my favorite unless I've got company).
