Well I did Waugh Chapel > Piney Orchard > 175 > 32 > 198. That route was pretty quiet until I got to the 295 exits... well besides that hill on 198. That got the breathing up a little bit.

There seem to be a good deal of group rides in my area. I think both of the Crofton LBS' do rides and on occasion I'll see a very large group of riders on Davidsonville near the park and ride. Is that the Baltimore Bicycling Club?
