That's the main reason we stopped going there. We were at the Cylinder Beach ground a few years back in winter and the place was virtually empty, but we weren't allowed to choose our own site, we had to take the one they allocated to us, which was way up the back of the park, when we wanted to be by the water. Anyway, we'd just got ourselves set up when a new group of people arrived and guess where they were sent? right next to us! For the week that we were there, there were probably a maximum of about 8 groups of people there, and all of them on top of one another while the rest of the camp ground sat empty.
It's all fun and games until someone gets hurt - then it's bloody hilarious!
