Prince William County
- Manassas and the sounding area, including Yorkshire, Manassas Park, The Sudley Area, Signal Hill and Bristow. These cities are in the northern part of the county, and Manassas is the county seat.
- Woodbridge — a major shopping destination for Potomac Mills Outlets. Near Dale City, on the southern coast of the county
- Quantico — A town on the Potomac. The other three sides are srounded by the largest marine base in the world, Marine Corps Base Quantico.
Otherwise, the main artery is without question I-95.
Sightseeing in Prince William County is overwhelmingly military-related: the National Museum of the Marine Corps and Manassas Battlefield National Park, both of which attract a lot of residents and other out-of-state tourists coming down from D.C.
The Potomac Mills Outlets are the other big regional draw, again bringing in the visitors from D.C.
