might as well do this in this thread. i grew up under one of the biggest ole miss fans in the world, and went there my freshman year, so here's some general information and advice for future reference.
the roads in oxford are small and usually extremely congested on game-days, so if you're planning on tailgating in the grove or parking anywhere close to the grove you might wanna try to get that out of the way early. otherwise, your party (or the driver) will get stuck parking and walking for 2 (or more) hours. and getting to the grove early is NOT a bad thing at all.
abners is a chicken spot in oxford and it is GREAT. i think that they have the best "special sauce" of all the college town chicken restaurants (zaxbys, sawyers, guthries, etc...). if you're planning a tailgate, abners can PUSH some chicken tenders quickly. their grilled tenders are scrumptious as hell.
you can't buy cold beer in the county, so make sure you bring a nice cooler and plenty of ice. although liquor is the much preferred beverage in the grove.
if you have to go to the bathroom you should probably start walking towards one as soon as you get the urge. there's some porta-potties around the grove, the UC, and the "Hotty Toddy Potty" but the line is usually ridiculous.
the girls in the grove are some of the hottest you will ever see in your life. so dress nicely and get your game up. i'm telling you, you will fall in love every 5 minutes with a different girl.
the grove is extremely fun and the grove-goers are very nice, so don't be afraid to ask for something or introduce yourself to anyone. you'll never see tents done up like this ever again.
the women can waste hours upon hours in the square at the little shops and what not. there's also really good eats in the square if you don't mind waiting on a table.
the bars close at 12.
if you're staying there for the weekend and you want some good late night junk food, ask about "chicken on a stick". it's brilliant.
