I don't know traffic-jammer.
"Every weather can be ridden through, if your prepared and calm."
I can't handle those real heavy snows. The subdivision is impossible, because the roads aren't plowed. I've circumvented that problem by walking the 3-4 blocks. Usually the main roads are plowed, and I can make it. But there's usually 1-2 days a year, when I just don't want to risk it. However, I almost always make the decision on the side of biking.
