We stayed at the Cedarville State Forest - Brandywine, Maryland. This is a few miles south of the DC loop which means that it is quiet and still close enough to drive in to the city. The parking sites are paved, as are all of the interior roads. Deer may wander through your parking area. Pets are allowed and they have a clean and modern rest room and shower facility, if they are needed. It is very wooded so be sure to ask for a site that will allow you to use your Satellite antenna. It is patrolled regularly by forest rangers to help you if you have any questions. Restaurants and shopping is a short drive outside the gate. Cost is about $25/day.
