Someone in our group brought a flag last year. First time we’ve had one. It was mint. Meant the wider group could converge in a spot together. Someone goes for a wee mid set? Not a problem, see you in 5 mins. Lots of people struggle with the idea of getting lost or separated from the group, this completely solves it. I’ve never really been a fan and wouldn’t want to carry it round myself all weekend, but banning them is ridiculous. Let’s be honest, the views generally shite anyway, people using the Elton John example a lot….He sat there for 3 hours, there’s nothing to see. Shut your eyes, dance and stop crying about flags.
