The big snow/ice storm amounted to a couple of inches of mostly slush on the trail. The bridges were a little hairy and the washboard-like snow debris from the plows made handling a little loose, but the ride was otherwise beautiful. What started as rain turned into snow by the time I hit DC. My new studded snow tires worked very well (although they were incredibly hard to put on-leaving me with a nice blister on my right thumb) and slipping and sliding were minimal. In fact, I only unclipped once and never had to put a foot down. That said, my ride was roughly an hour long compared to my usual 25 to 30 minutes. What a blast though! I chatted with two other riders and saw the tracks of two others. There were stretches where my were the only tracks on the trail and the glow of the streetlights in the snow againts a dark, ominous looking sky made for a surreal and beautiful commute. The slower speeds along with a lot of spinning kept me fairly warm too.
