Bamabuzzard - I don't think the folks from Meridian (or Mobile, or Biloxi or anywhere else) are the ones that Coach Saban is specifically addressing. Those few who may hit the road for personal reasons don't leave "huge, empty gaps" in the stadium.
I know quite a few students who attend the University right now & most are in the "Greek System". They ALL talk about attending games until halftime or shortly thereafter, & then leaving for their designated Frat/Sorority houses. Once there, they continue to watch the game on a huge TV and indulge in "whatever they can put their hands on"!
I'm just amazed that the highest paid coach in NCAA football (with the currently ranked #1 team in the nation) should even have to ask folks to stay for games. I guess everybody is different. When we make the drive from Mobile, we stay our "happy little butts" in our seats until the game ends. We then hang around a bit for the traffic to thin before heading home (and yes, we've driven home many times during the early am hours). It's tough, but well worth it.
