if its that good a place, it might be worth the effort to try and find out who owns the land, and then go and talk to them and politely ask if you can use it from time to time...
A little bit of effort and consideration can sometimes go a long way with landowners, a lot of people choosing to just trespass sooner than ask permission...
You never know, you might get a result.
If it is the P&P site that rseaville is talking about, then result you have got a pretty cheap fun site on your doorstep when its open.
If others regularly trespass on this land which might be private property, you could suggest to the landowner that you would willing patrol the land a few evenings a week, with the owners permission and gather info of those unlawfully trespassing to be forwarded to the police. That way you get to go play with the your truck whilst doing your "job", with the owners permission, and he can be rid of the assholes who choose to drive all over his land.
