The George Washington National Forest is just down I66. Take I-66 to I-81S and pick up Rt 55 (exit 296) towards Wardensville, Wv. Drive 17 miles and turn left onto the unmarked gravel road (at the top of a hill, just past a white house on the left side). If you hit the WV border, turn around, drive 1 mile and turn right onto the unmarked gravel road. This area is called Vances Cove. From Manassas, it takes me right at 1.5 hours to get to our usual campsite (just over 5 miles down the unmarked gravel road).
It's wrapped up in squirrel. There are coyotes up there as well. I've heard them, but not seen them (others have). Bobcats have also been sighted.
In addition to squirrel, there are plenty of grouse, deer, turkey, and black bear. I haven't seen many rabbits. Every year, my hunting group (between 5 and 8 folks hunting) take anywhere from 2-6 deer out of there. Other "camps" have similar success.

There are several WMAs near NoVa, but I haven't hunted any yet. I spend most of my hunting time in the GWNF and Jefferson National Forest down around Roanoke.
