Good news and good day for me. My bruising has subsided to the point where I can ride, comfortably, again, without aggravating anything. Did two miles of heavy duty plowing and pedaling though deep crusty snow out on the lake (whew!), then added another easier pedaling mile, riding the shoulder of our snowy neighborhood roads, being very careful to stay off the well traveled and slick portion of the snow pack. Still need to mount the studded tires on one of the fat bikes, but can't decide which one gets the studded. Kind of OCD, maybe, but hate changing out tires on the other bikes because each kind of tire and tread has its place for various types of winter riding I do. That, and I hate doing the switch out tires thing.
