Thanks! I have another question, Timetide, for you...
You cycle all year--how do you deal with snow on the ground? I worry about ending up underneath a car.
There are usually only 3-5 days a year when I won't ride. (Last year the winter was so warm and there was so little snow that I didn't miss any days.)
You are right to be cautious around cars in the snow. I would ride in any amount of snow if there weren't cars in close proximity! But a big part of it is building up confidence and riding technique slowly in quieter areas before moving into heavier traffic. Also, I think some of the most dangerous times for a cyclist are when the roads are wet and it's just around freezing . . . it's very easy to be surprised by ice in that kind of weather.
There are some simple tips to help in snowy/slippery conditions: don't make any sudden moves, especially turns and don't panic-brake if you can avoid it. Surprisingly I generally find drivers more considerate in winter weather. (I think partly they respect that we're out in the elements and they're protected and warm.) But there are still drivers who don't understand how to give cyclists enough space in inclement conditions.
Anyway, those are some suggestions off the top of my head.
