I find It's always a rough transition when you first get snow. I'm so used to having traction I can rely on to bust moves around cars. Today was my first day of real winter riding, and it was a little scary. Ice EVERYWHERE, and blowing snow. Couldn't even touch my brakes on a lot of sections. Did a couple of really nice, semi controlled 2 wheel slides. Sure got the heart rate up, not from the excercise, but from the fear of death. Maybe it's time to build a mtb beater....I'm to old to ride 700x28c slicks in the snow. It is nice to have enough power to spin the rear tire though-makes me feel like a muscle car!
Good luck out there, and don't let those cars take advantage of you.
