Having lived in Jacksonville for two years, I can tell you that there are a ton of Georgia alumni in that city. No way it is 8:1.Yes. Jax is 8:1 gators to dawgs as a city but the crowd is 1:1 and the tailgate is close.
And you are right that it doesn't matter anyway. I've been to those games a bunch of times, and the crowd is always 50-50 - divided lengthwise with Georgia on one side and Florida on the other.
It's like saying Oklahoma-Texas is favored toward Texas because it is in Dallas. Nope. Crowd is 50-50. Oklahoma (and Georgia) would never stand for something that is tilted toward the opponent every single year.
