Not specifically Mustang, but each Friday night from mid April to mid October, the Prince William Cruisers sponser a cruise at the BJ's Wholesale Club parking lot in Potomac Mills, VA.
Time: 6:30 to 9:30
Directions: From I-95, take the Prince William Parkway toward Manassas; go (approximately two miles) to the intersection of the PW Parkway and Minneyville Road. Turn right into BJ's parking lot. You'll see the roped off area and hear the music. Lots of cool vehicles show up at this cruise, running the gammit from old to new - customized and restored. This is a great place for car buffs to hang out, enjoy the summer evenings, and talk cars.
Also, there is a large cruise at the Burger King in the Nokesville area every Saturday afternoon - go toward Manassas on Route 234 to South on Route 28. Take a left at the next intersection - you'll see the Burger King on your left.
