After being directed by one marshal to a day visitor gate, I returned to him and overheard myself saying "Fuck off, I'm camping in here". I ended up in the 'quiet' field. BMF control told me there was a pedestrian gate to get into the main caping area, but I found it padlocked with a car leaning against it. I think it took me about 30 minutes after entering the showground to actually find a pitch.
