Thinking off the top of my head... among the "BCS" conferences.. my perceived college towns are ..... ACC = Chapel Hill, Charlottesville, Boston, and perhaps Blacksburg and Clemson. Big East = none that I can think of.... perhaps South Bend and whatever town Rutgers is located. Big 10 = All of them except Lincoln, Columbus, East Lansing, and Minneapolis. SEC = College Station (I guess), Auburn, Tuscaloosa (maybe), definitely Oxford, Athens, Gainesville and Starkville (well maybe) ... and perhaps Columbia.
I'll leave the Big 12 and Pac 12 for someone else... Im tired of thinking right now
