One of the away games I went to was @ Starkville one year. It was pre-expansion, like a big high school stadium. They needed those cowbells so it wouldn't be mistaken for a library.
*edit - looking it up, it was 41,000 when I visited. It was just both sidelines and one upper deck. I'd never been to anywhere smaller than the Gator Bowl (70K-ish) before then. Between the Swamp and my high school stadium, it was closer to my HS stadium.
Went to Brice-Williams, Neyland, Tiger, Citrus Bowl, and Tampa. So yeah, it was tiny.
