You are either in a different part of the province than I, or are looking at a different forecast.
Or you're going to be riding in the rain.
Meh, I always say...ride to conditions. Conditions can be slippery, there can be crap on the road, and tires can be cold in October too....that doesn't mean I don't ride in October.
Other drivers? I see no difference in behaviour in January vs July - the "people aren't used to seeing motorcycles in the winter" thing doesn't hold water with me - I always ride as if cars don't see me anyways.
The salt thing is overblown. Contrary to popular belief motorcycles do not collapse into a pile of rust if they get some salt on them.
