I'm in MA as well, and I can imagine you were on some pretty chopped-up, rutted snow/slush. It's awful terrain for a bicycle and I've had some tense moments lately as well. I'll ride on it most of the time anyway, but if it's really bad, I simply don't go to work until conditions improve-- which is sometimes in a matter of hours, sometimes a whole day. I try to stick to this policy despite the fact that my work pretty much requires me to be there during business hours, but honestly, I don't think I'd be worried about that in the back of an ambulance (or worse).

This winter we've really been getting pummeled with snow it seems. Whatever you do, I wish you the best and here's to the eventual coming of Spring
