There's not much around Hampton roads aside from private properties. I know there's one place out relatively close to you but I haven't been there in years so I don't know what condition it's in now.
Here, though, the cops are pretty strict about it. I've heard of guys getting slapped with reckless tickets, trespassing, and EPA violations (usually they fire you for EPA stuff if you were wheeling on a buddy's land then go on the street still muddy). I'm thinking Chesapeake, Suffolk, eastern shore, and Yorktown/Gloucester would be your best bets. I'd be down to go if you find anything, though. The place I used to go to in VB is now a parking lot and retention pond.
