When I was a kid I'd ride my dirt bike year round. No windshield, no face shield, no problem. The best days were when the road was covered with snow and school was canceled, the deeper the better. They show flicks like "On Any Givin Sunday" where they get to play in the sand. My buddy and I would tear up the streets in the snow.
Now, I live in Ohio, when the salt hits the streets the new, expensive, streetbike is put away until spring rain cleans it up outside. We're not wusses, were just riding the old lady instead.
