Uneventful ride in last night. Cold with a few flurries. this morning's ride home was colder with a dusting of snow. I stayed warm enough but the ride was lacking something. I got into my driveway which is pretty much solid ice with a dusting of snow and decide to "play" a little. I hammered on the pedals and spun the rear tire. It quickly got out from under me and started to come around. the front tire started to slide with it and I was sure I was gonna go down. By the time I got my foot out of the clip I was already straightend out. Somehow I managed not to fall but I did rip one of the stitches in my back loose. I'm sure by now my Dr. hates me.
