This is crazy talk, but you guys make me want to get off my rollers and go out and ride in cold weather!
Hey no-racer, you have some really nice rides on route-slip. I have often done a "tour" of sparrow's point myself when there is more light out-- its my favorite for after work. In fact, I got puncture resistant tires expressly so that I could ride down there without getting multiple flats.
Since I'm here, has anyone ever done Franklintown and Dogwood roads to go westbound out of the city? I've been thinking of adding those to my little repertoire of routes. They are long rural roads but I don't have a feel for how safe/convenient they are. Basically this route (but backwards and I would probably avoid starting on Franklintown at Frederick road).
