I am leaning towards this view, and I would definitely go for a killer lineup. I always heard horror stories from years ago about ditches dug in the back of the grounds where there was a river of piss and waste, but maybe that doesn't happen anymore. No way the wife would be up for it though.
She can stay home.
Oh they do have the ditches, it's just a matter of camping nowhere near them, which is easy if you show up on Wednesday instead of Thursday. We were fairly close to one of those in 2008 but definitely had no problems. Most people just find a bush to pee in instead.
