Bike Night to benefit returning soldiers

Cheeseburger In Paradise restaurant is holding a weekly bike night to benefit TAPS (Tragedy Assistance Program for returning service men and women). I’m looking for clubs in Northern VA to contact. The event has started with some great success, although we want to keep it strong and raise solid money for this organization. Event is free.
Looking for contact information for clubs in No. Va.

Thanks.
