It has warmed up to -17 F / -27C already and we are supposed to warm up to 0F / -18 C this afternoon... I have a bunch of errands to ride today but it should be pretty pleasant.
The worst thing about the winter commute here is the roads... thankfully... there is no snow in the immediate forecast and the city is supposed to have all the main routes finished today.
I live on a bike route and only saw one guy riding this morning... at these temps a lot of people have reached and exceeded their personal cutoff point for riding... at -25 C the combination of temperatures and road conditions generally result in people looking for other travel options.
I have no cutoff point at which I won't ride and -46 C / -50 F is my personal best... if we see -50C I'll have to see what riding in that is like... that is -58 F.
