Nobody. Goes. To. Their. Games.
My first year at MTSU, they hosted Minnesota. There were more Gopher fans tailgating and at the game. Nobody cares.
I know plenty of Western fans that live in Nashville. Davidson, Robertson, and Sumner Counties in Tennessee get in state tuition to go to WKU.
Just providing my first person observations of WKU in Nashville, as it stands now. I know plenty of people who attended WKU and live in Nashville. Heck, I got a Master's from WKU so I guess I count. What I'm saying is I don't see people wearing WKU gear, I see them wear Titans, Preds, UT and MTSU gear everywhere. Maybe things have changed since you lived here.
