It's a great idea. It's just hard to inforce. I mean, the only time your cooler is searched is when you walk in the gate. If beer is found in a cooler, the checker would then have to look at your ticket to see if you are in one of those sections.
Also, everytime someone buys a beer from the racetrack the attendent would have to see their ticket. And there's noone seeing the beer people stuff in their pockets.
EX: Last Oct in Atlanta. I saw a van with about 8-10 guys in it, they parked in the row infront of us, and they had a cooler full of beer. Not a big thing, we see it all the time at the tracks. But one guy got out, he put a beer in each of his coat pockets, each of his front jeans pockets, & even had a friend carry one for him.
So, yeah it's a great idea. And I am all for it. It's just very difficult to enforce.
