I'm heading into my fourth winter now. The main part of my routine will be building up the winter bike. Right now it's configured as a mountain-bike, and it's on loan to a friend's kid. Sometime between now and snow, I need to grab the bike back, swap in the rigid fork, put on my rack and fenders, put on my lights, and mount the studded tires.

I'll go over my clothing too. I can't say that I have everything dialed on the clothing front. Winter weather has wide variations and throws lots of curve-balls at you.

In fact, your post reminds me that I need to go over my winter clothing period, not just the biking stuff.
