have camped at bsj for last two years and had great fun never any problems apart from a very drunk lad trying to knock down a tent on one of my pals by taking out tow tent pegs accidentally until he stumble to his bed for the night, a patch of grass (face down) just past our tents.
on a serious note they had a free bus from the front of the campsite to the circuit entrance on the inside of the track.
