Actually there's a theory that winter commuters get sick less often, and if we do get sick, we don't get as sick for as long. I don't know if there's any merit to it, but I certainly don't get sick as often as my co-workers, or even my own wife.

Low 30sF for me today. Overcast. Tailwind pushing me along. Spotted some dude in a duck blind in the lake. Saw a couple of cyclists and some peds on the MUP.
