-47F here this morning!
naisme, bro, I thought you were doing your longer commute last winter in even colder weather. I won't call you a wimp, but just wondering. I do think it wise to forgo the bike in favor of your safety.
I've not been able to commute by bike since right after Christmas. We have had over 15" of snow and rarely seen temps above zero for the day time high.
Be safe, stay warm.
Bob
