Snow stopped play, which was always a possibility at this time of year. I was out for an hour or two on my own yesterday, and the conditions were pretty baltic. It actually wasn't that bad riding in the cold weather, but the thermals add an extra layer which makes me feel like the michelin man, and even with all that my fingers started getting a bit numb.
Cleaning the bike afterward wasn't that bad, at this time of year the salt tends to collect and harden on the bits of the exhaust but a bit of clean water got rid of that.
