One time a few years ago, days after seeing any ice on two of my main routes, I took a third route for variety. I was booking pretty good on my street tires fighting the morning glare when I entered a shady parking lot behind a boat house by a lake. The bike slid out to the right and by left foot somehow came out of the toe clip and I slid about 20 yards like some dirt-track motorcyclist until on the far end, by tires caught dry pavement and my bike righted itself and I braked to a quick stop. I suppose had I been in my 20s or 30s I would have been thrilled. But having reached 50 I was scared, upset from not seeing the danger beforehand and sore from the stretch (!) So now I'm a little more cautious. However..thanks to Bike Forums, I have been able to push my cold weather biking threshhold back down to 12F; and I plan to get studded snow tires for next winter and return to riding in the snow for the first time in 15 years (although this time, smarter, warmer and safer) Thanks BF!
