How did they enforce the admission fee? Can't figure out how they logistically did that with such a huge area. I think the admission fee is a bad idea, but if they're going to do that, I think they should put the headliner on a reasonable hour. I would have loved to see UB40 in person, if I were there, but don't think I would have paid because I assume they didn't come on until like 1 AM, which is the norm, and that's too late to start, for me..
