Check Arrow Bicycles (
www.arrowbicycle.com) at Hyattsville (a couple of miles south of College Park). They also have sunday morning rides. 34 mile ride around College Park/Hyattsville. Cool bunch of guys. No drop ride, slow sub-group averages 16 mph pace, I don't know the pace of the faster group as I have never been able to keep up with them. I'm not going to be able to make it next week, but if you decide to join let me know week after the next.
And welcome to the area.
