Why not just have parking divided? sections for every scene or what ever you want to call it. doesn't even have to be in the same parking lot ether. if your into performance then hell you know where to go. if you into audio then you know where to go. and if your just a dumb ass have a place for the clueless to go too. that way you can divide it up a little and segment the "import scene" cops will get a jist of whos the trouble makers and whos not. Thats the way it is in foreign countrys.....
