I was so impatient to ride a longer trip, that I went ahead and hit the confluence trail before the snow had entirely melted off.
Mostly there was enough clear to keep me out of the snow, and was never worse than this:
However there was a section between Ridge Street and Riverfront Park, where the trail was still covered in about 2" of wet slush-bottomed snow, so I plowed through it, just for the experience! I quickly discovered two things:
1. That slushy icy snow instantly collects around the brake structure and stays of the bike, and the rims of the wheels.
2. Even with my cantilever brakes and alloy wheels, my front brakes took a vacation for an extended period of time.
I now feel it's time to go spend some $$ and get the kool-stop salmon pads that everyone seems to recommend. Slowing down slowly, even with a gorilla-grip on the brake lever, could be quite frightening in the wrong place.
The actual pedaling through the snow however, wasn't really all that bad, even without fenders, though the rear rack and double-daytripper panniers stood in to keep the snow and crud off of my back.
It was definitely worth it though, since I had the MUP almost to myself. (remember to right-click images below, and select "view image" to see them full sized!)
