Nice to see you at Otley Raggy. If you can't beat noisy b*****d's on the campsite I suggest you join them with highland war pipes (lots of them), Oakley's fan club the DGP's, a herd of buffalo, several mating cats, Colin's mums budgie (it's loud!!)& a primary school recorder group. Should make a cacophony enough to send anyone running a mile! Failing that I could always mix up a nice concoction to put in their water bottles /coffee cups/ beer which would put 'em out of action for a while!
