Day pass = bad idea. People too cheap to pay the full fare are also too cheap to spend much money at the vendor booths. The fixed costs of the rally (site rental, porta potties, showers, tents, golf carts, etc) need to be covered regardless of whether people stay one day or six. Other than wristband checks at the gates and beer tent there are no other credential checks. There are already at least four wristbands (attendees and vendors, over and under 21), each days day-pass would require at least 2 more colors (over and under 21). As it is, security is so busy once the event gets started even cars (that should be parked out of the venue) are allowed to remain. TSA-style checks at all the doors?
