I met a rep from Bike Baltimore today at Bike Jam 2009. I’m not sure who it was, but I think the dude gave me his personal copy of a bike map because I asked if he had one with road grades on it and he pulled one out of his bag and gave it to me.
Thank Bike Baltimore! You saved me $6 that I was going to send to UMBC to order my own.
