My advice then is to go to
www.cyclingcentralva.org/forums, introduce yourself, and say that you would be interested in joining on group rides. The MB community around here is very open and welcoming. They don't care what you ride, as long as you ride. Another good way to meet people to ride with is to do trail work. There is another 2000' of trail being added to Northshore, and building starts this saturday. Meet at 8am at Crossroads Coffee shop (on forest hill ave) if you want to get breakfast before, or meet at the Texas Beach trail head at 9am (with gloves and h2o) to work. There is a trail work forum on the site, and I can almost garuntee that if you start doing trailwork, you will meet people to ride with real quick. Also, I would offer to take you myself, but with the weather and my crazy schedule, I never know when I'm going to ride until its time. What do you ride, in case I see you on the trail?
