we were at the game this weekend too - sat in section M. Everyone around us was great and friendly. We got there about 2:30 and met some people in the grove who had a tent set up. We walked around a bit as well, and were checking out a watermelon carved out like a sharks mouth, with a stuffed elephant in the jaws - the lady who apparently set it up came out and greeted us, offered us some food, and gave us some water. Had multiple people tell me "welcome to the grove" or "welcome to Ole Miss" (we were wearing Bama shirts).
There were 3 ole miss guys sitting behind me who literally were cracking me up the whole game and we had some great conversations - one was trying to bet the other we would score over 70 by the time the game was over - they all seemed to be realistic of where their program is and ours - they had all hoped to be more competitive, and were disappointed in how their team played, but all showed great southern hospitality.
Overall, we had a GREAT experience - I wouldn't EVER want to sit near the other teams student section in any stadium, and that was probably the difference. I recommend going if you haven't done it, great venue.
