One winter I enjoyed taking a shortcut through the mall parking lot in the morning (before traffic got there) just to practice my swerving.
Last winter's best moment was the morning after a fresh storm. I had just reached the far side of an intersection and got too far to the right, where it was slick. My wheel started heading towards the snowbank on the side, and it was too slippery to correct it, so slowly and gently into the snowbank I went! Didn't hurt a bit, and both I and the motorist behind me got a good laugh out of it.
Eat your hearts out, Californians!
