Mid to high 40's this am, so there were a lot of riders out this am. You can certainly tell the folks that don't commute year round. They are bundled up in many layers, and that also includes full face balaclavas, and shoe covers. (Not a slam by any means, just an observation) But, they are on their bikes, so good on them.
I saw one of them on my way in today, he looked like he was realizing he didn't have that much to be terrified of when I went by.
