Due to the construction of the new high school, the preferred parking/access for the turf field is behind the Northern Virgina Center/VT Campus on Haycock Road. From Route 7/Leesburg Pike, turn onto Haycock Road towards the school. Turn left at Falls Church Drive. Take the second left into the parking lot, gates are open on the weekend.
