Yeah, great that you commuted! I haven't commuted since October 30th!
Just FYI - on Sunday's the BP doesn't open until 12 noon. There is their regular Sunday a.m. ride that departs at 8:30 (unless it's wet/raining/snowing, or below 28 degrees) and return around 10:45ish to hang, chat, drink coffee, and schmooze until the shop opens at noon. That ride is a true hammer ride - I think the term they use is "spritited." Hopefully, in the Spring, I'll be in shape enough to hang with the B-group again. Aicabsolut - that might good a good group training ride for you to get in with.
I'd also be up for a casual ride. Still hoping/planning to get my mtb out on the C&O.
