Does anybody else but me not worry about getting wet as long as they stay warm? When I read all the posts about rain gear I keep thinking I must be missing something.

I suppose it depends on what facilities you have on the work end of the commute? I just wear whatever weight jacket I need for the temps (assuming colder due to evaporative cooling) and then either hang stuff up to dry or if stuff's really soaked, toss 'em in a dryer (upstairs apartments have coin-op) for a bit.
