My parents were driving through Glastonbury several years ago on the run up to the festival. They had a bad time of it: people banging on the windows demanding to be taken to the festival site. They both found it extremely intimidating. I would not like to be living anywhere near the place around festival time!
I have a lot of respect for the amount of money the festival makes for Water Aid and Oxfam - and my partner spent ten years working for free as an Oxfam steward and then supervisor - but I find any sacred space is compromised with such huge amounts of folk around. Especially when some of them are such idjits and enjoy bullying elderly folk.
