When I used to live in NoVA, I hooked up a couple times w/ a bunch of sportriders. Ask a for a guy name, Tony. I believe he's one of the leaders. He lives in MD and rides a R1. They seem cool and introduced me to 211!!! One of the best roads in the area. It's off of 66, near Shenandoah. It's very smooth. They usually congregate at the Shark Club in Centreville or Hooters in MD somewhere. Your best bet is to hang out at the Shark Club in Centreville on either Sun or Sat. morning. Best of luck. BTW, they are EXPERIENCED riders, w/ an awesome selection of bikes, but they also look out for the riders in the group.
