Looking for Easy Off-Road Trails Near Northern Virginia/DC Area

[How Much!!]

I would like to give my 2005 H2 some off road time, other than parking in fields. Thus, I’m looking for some beginner trails near Northern Virginia.

I’ve looked at the GW National Forest, that looks good. However, they have little information on their Web site and I really want to find a set of trails that will keep me out of trouble. Rather not scratch up, or damage my Hummer just yet.

Also, I would be happy to learn about trails that are closer than GW. The forest is a couple of hours away.

Thanks.
