Winter has just started to show its face around here. Maybe some snow Tuesday and Wednesday with highs in the teens (F) toward the end of the week. Nothing that will stop me from riding though.
I do have a problem with my goggles icing up once it gets below about -10 F but I've ridden when it's as low as -21 F. We don't see that mythical place where F and C meet in the Twin Cities like they do in the Northern part of the state but I know I'd have to figure out my goggle problem to be able ride when it's that cold.
