I live near Fredericksburg and have seen some GWs on Sat nights meeting at Chick Fila on 610 but have never managed to stop in with them. The locale GWRRA clubs are in Fredericksburg, Mananas, Leesburg, I think there is one out in Winchester by you, they may have a better idea of who meets when.
Fred used to have one put on by Big Daddy Leather but they closed so IDK if anyone picked it up or not. The local gwrra chapter meets at golden corral at 4 mile fork in spotsy.
Winchester has a chapter too, but idk where they meet or what night. I'm down closer to Harrisonburg and IDK of any bike nights that are a regular thing, just a once in a while put on by the Honda dealer.
