Tonight was my first ever sub 0 (just barely) temp commute, with snow on top of it. Great times, after the first 5 mins I felt great temp wise and stayed that way the whole commute home. I also learned how great it is to have snow reflecting the light, I rode all of the MUP with no lights on front because of how much the snow lit things up, just turned them on for the sections near roads.
As an interesting side note, I work at a bike shop and even had my manager ask me twice if I wanted a ride home...
