Me too Phoenix.Litter,fly tipping ,waste is my absolute major bug bear.I simply don't get it.Ever.Never will and justifying as a means to get into a festival and earn some money.Sorry don't get that one either.All my DCs have been to festivals,admittedly not Glastonbury but several other big ones.They all came back with mud caked gear and sleeping bags that all washed and we're fit for purpose again.Tents were cleaned,and if in too bad a state disposed off in our rubbish.Don't care what taste in music ,or political persuasion,deal with your own rubbish wether at a festival,or just generally.But then I have been known to tackle the lads that seem able to carry full bags of food and beer to a local beauty spot,and yet can't carry them away when emptied. Politely.
