As much as I would love to be able to commute by bicycle all year round today was the day that I had to draw the line.

Overnight some 10cm of snow had fallen. I deliberated for a good 10 minutes as to whether or not to ride. I made the decision to do it. Got all my gear on. Got out the foul weather bike with the 35mm spiked tires and fenders. The roads had not been cleared. I rode for about 1km and then decided to turn back. The bike was too unstable, even at low speed. I had to hang on to the handlebar quite tightly. The back end was also all over the place. I decided it was too dangerous and wasn't worth the risk. This is my limit.

So those of you who have to commute a good 10+miles, how do you deal with it under these conditions?
