Tough ride in this morning (from the west) because the plows hadn't done the paths yet. A good workout! And the residential streets are brutal with all that slippery "brown sugar" mixture of snow, salt, and road grit. My cheap fat knobbies are sliding all over the place. I suspect studs wouldn't help much in these conditions. Does anyone have tires that are giving them decent traction on the streets? I've even gone against policy by riding on a few sidewalks since most of them are shovelled.
