dd (14) is talking about wanting to go to a music festival this summer: to be clear, it's Wireless in Finsbury Park; there's no staying overnight there, and we live in London anyway so it would just be going for the day. There are issues about who she would go with as under 16s need to be accompanied by over-18s and I'm pretty sure she will not want to go with one of us but leaving that to one side, we're trying to work out how concerned we should be about safety issues when working out what we think. Is this basically a reasonably safe environment, or basically a not very safe one at all: what do MN'ers know about the "non-residential" festivals (they must surely be a bit different from the Glastonbury's of this world) from a safety point of view - drugs, alcohol, theft/mugging?
