When I first started buying season tix in 94, SEC games were $25. Non-SEC were $20. At that time, you pretty well paid face value to buy on on the street outside the stadium. Last year, as the email said, finding a bargain outside the stadium was easy. They didn't even sell out season tix packages last year.
Factor in how they've made tailgating on campus so difficult, the economy, and I gave up my tix after the 2007 season. Hate I wasn't there for the 2010 season, but the days weren't at long, the games are good on TV, and the food and drink is convenient. That sort of makes up for what I'm missing in person and at the tailgate...a little.
