Strava? The Climbs - surprisingly. Rolling. Nothing too extreme. The WO&D is pretty much all uphill. Going up river - well, up-stream.
Strava (
http://www.strava.com/) is similar to MapMyRide, I just happen to be a major fanboi of it. The King of the Mountain achievements are really cool to me. I might have to do a ride down the Mt Vernon down to your hood this weekend and check it out.
