I made the commute this morning, but it was one of the rougher rides I've done. It was surprising how bad the streets were.
It could have been worse, though. 14F and 4 inches of fresh snow, in all variations from pristine, untouched snow on unplowed streets to car-trafficked slop, to piled higher in inopportune spot locations that made for fun little surprises.
It was more work pedaling, which is okay since I need the workout anyways. The sliding around wasn't so bad on its own. The doing of all of that out in traffic with cars was what made it more stressful.
