If you go to Whiteleas , head down the road towards the train crossing, when you get to the round a bout where you can turn right towards asda .. take a left instead and look on your left hand side ,, you'll see a load of hedges and fields. About 2 turn offs up there is a car park. Its open but pitch black, you can see cars turn in so have a short warning. I've banged a couple of lasses there. Dont go now but its an ok place.
Also, the dirt back roads next to bede's world.
