Gaad I get tired of the Nanny State mindset. What the hell is next, making fans in the end zone wear helmets in case a field goal or x-pt might hit them in the head.
If they're actually worried about their kids getting black out drunk then put a dozen extra cops strolling through the tailgate area checking IDs. If they did, they could issue 50 MIP tickets without even trying to find any. Or they could issue 500 per game if they actually sought them out.
If they're worried about legal age fans causing trouble in the stadium because they're too drunk, then turn them away at the gates when they attempt to re-enter. Make it known that clearly intoxicated fans will not be allowed in. Those fans are supposed to be out in the parking lot anyway keying Alpha's car.
They can address any issues as is. They don't really need to remove the tailgate option. This is just more silly sh*t to be politically correct. Therefore, it is highly likely it will become policy.
