Here in Boise, we're fortunate to only have maybe 2 or 3 weeks' worth of days each year when peoples' jaws drop as they ask, "You rode your bicycle - today?!?"
The "morning ride" was borderline. Fat, wet snowflakes coming down steady, and starting to accumulate. Temperatures near freezing.
Other than the snow that accumulated on my shoes and britches as I rode, no problems. Traction was fine and traffic was mercifully light and slow-moving.
By contrast, we have 100 or more days every year when the weather is so nice I want to ask people, "You're driving your car - today?!?"
