Hey distance folks! This weekend I'm riding up to around Burkittsville for camping fun with non-bike friends. Sunny! Upper 70s! Anyhow, wondering what y'all thought about routes. Looking at either taking Old Frederick straight across, cutting west to the C&O (meeting it just down from Sugarloaf Mountain), or maybe just maybe catching a ride with a friend down to DC and riding all C&O up. Also, I ride straight-up road tires now and I'm not going to go out and buy cross tires before the weekend--is the C&O even advisable on skinny tires?
