Ticket prices used to be cheaper. Adjusted for inflation, I think they were still a lot cheaper than today. Concessions weren't nearly as expensive, either. And you could park in any one of the deserted lots around Midtown for about $5 or so.
I think ColoradoJacket hit the nail on the head. When I was growing up (no cable), Tech was on TV maybe once or twice a year, when they played Alabama or UGA. After joining the ACC, they were on TV a little more (JP Sports Network), but now you can catch even the cupcake games.
Years ago it was a big deal to go see a college game, whether it was in Athens or at Grant Field. The Tech campus wasn't far from where I grew up, yet it still seemed like a huge adventure to go "Downtown" and see them play.
