I\"m Young, but I\"ve read alot...
prior to the 60's and 70's Athens was a minimum 2 hour drive from ATL on 78 or 29.
Since ATL was the hub of business in the Southeast, Tech and Grant Field had the largest stadium in the South. Remember, there were several rows of bleachers placed on the running track all the way around.
Grant Field didn't go over 60,000 total seating until 65-67 according to the book Story of Georgia Tech.
As such, GF would host double headers between Tech-Georgia and somebody else. Rumors are that it would be packed for the Tech game, and half full for Georgia.--(sound familiar??)
Anyway, much like Auburn, once the limited access freeways were built, it became infinitely easier to get to Athens. combined with the "malnutrition" of the GTAA from 75-83, and you have an entire generation of Tech alums, and 2 generations of native Atlantans that don't understand how and why Grant Field is the most special place in Southern Football.
Alabama may be the Glory program, but Grant Field was Southern Football's showcase...
