Coldest ever: -23C Today: -18C
I live in London, Ontario, Canada. London is located in a warmer part of the Country near Toronto and the US border.
Because I try to ride year-round, I have all the gear I need to stay comfy. Best advice I've got is ski/motocross/snowmobile goggles. Taking good care of your eyes makes all the difference in terms of comfort in the cold. Truly cold wind seems to dry/burn eyeballs in a really awersomely nasty way.
