Late to this party but this is the way I understand it.
1. Univiersities follow city/county ordinances.
2. Starkville is wet for liquor and beer. Oktibbeha county is dry for beer and wet for liquor.
3. Part of campus (frat row and sorority row) is actually in the city limits of Starkville while the rest is in the county.
4. In order to sell (or legally posses) beer in the stadium, MSU must petition the state for Davis Wade to become a resort at which point it could set its own rules.
5. Ole Miss did this years ago is the reason they can sell it. USM is fully within the city limits of Hattiesburg which is wet.
6. I have no idea if they are working on this or not and if they are not, I have no idea who is stopping it.
7. I do not know why they will confiscate a flask at the gate when they allow liquor to be stocked in lockers.
8. No matter if you are partying in the Junction or mixing one up in club level or the LFL, just don't be an ass and cause them to crackdown on what we've got now.

I remember years ago during one of the crackdowns out in LFL the year after somebody poured a beer on an Ole Miss outfielder, I saw a guy stopped at the LF gate who was forced to pour out at least a case right there at the gate. Turns out, he was big guy with the university or the university system. A VERY big guy. About 2 games after that incident, the crackdown was suddenly and unexpectedly over and baseball water was freely flowing again. Funny how things work isn't it.
