Ideal Snow Conditions
Some of the most enjoyable winter cycling is when there is a slick coat of ice over everything. All the automobile drivers stay indoors, so you get to play in the streets safely. You slip and slide, but it's OK, because you can always put a foot out at an angle, and be a stable tripod.
It is also fun when there are a couple of inches of snow covering the back streets with many car tire tracks. As you ride, your front wheel jumps several centimeters back and forth from one car track to another, but you've become used to that, and enjoy the weirdness of the 'track jumping.'
Agreed?
