Slades park did close because of a death on the trail. Last I heard, it reopened sometime last year. You have to own property and have a permit to ride on the outer banks now, from some kid killing a wild horse a couple years ago. There is a park that just opened 2 years ago that is on the way to Corolla, right after you get to the NC border. Its a huge piece of land that has a few tracks and trails on it.

Other than those, there should be alot of places to ride in Suffolk, its all on who you know.
