Dirt Bikes Videos

Where do people ride their quads and dirt bikes?

I'm getting a quad (hopefully) soon and was wondering where people ride? Im pretty sure that it is illegal to ride somewhere that is not their property, but where people ride? I've seen videos of horses everywhere. When I travel: I have this path in the woods behind my house and leads to the house of my friend. My friend has a single track 0 so it is pretty decent. It extends into different tracks, but he has not done yet. I live in NJ and I was wondering where you ride quads and dirt bikes?
