It was Gullett Quarry, and there were enough visible bottles to make me wary of the hidden ones.
The warden was a really good bloke, we chatted for some time. His job, poor sod, includes litter picking the morning after the local youth have partied in the carparks etc, leaving all sorts of rubbish. Mind, that morning they had left him half a case of beer by the quarry so he may not have minded. Plus towels, food, discarded knickers, etc.
His opinion seemed to be that middle-aged people in camper-vans staying illegally dissuaded the youth from being too obnoxious, so we were a good thing. Also, we don't litter.
