the idea of paying a premium for lawn chair seats in the lawn chair section, or paying a fee upon arrival for bringing your lawn chair onto the concert grounds is a great idea. Sadly, the way the universe works when bluesfest is on, it'll probably come back to bite standers in the ass. Organizers will probably hear the idea, and think "well, standers want their own space, standers want to be up front, standers want to hear and dance, well THEY can pay a premium for the better viewing points" it's easier to wristband a person than a chair i'd think, in their eyes anyways.
