That's one of the problems I've come across at festivals, the question of access.

People live in the village/town all year round but for one week (or so) a year, they are prevented from accessing one area. Although residents are usually given access tickets for most of the day, these cease to be valid after a certain time. This is when you get locals who would not have set foot in the field/park at any other time of the year, arguing that it is 'their' field and they have the right to walk across it.

Ho hum...
