I thought I understood the mentality of fans - I did grow up in the land of "Gueaux Tigers" and "Who Dat". But... I seriously did not "get it" until I moved to Alabama. "Roll Tide" (and "War Eagle" to be completely honest) are spoken as often as "Hello" in this great state.
Joey was recently stocking the shelves at our local grocery when he looked up and greeted a customer (decked out in crimson and white) with a hearty "Roll Tide" - at which time the customer made a point to report his "good service" to management and he earned a free sandwich! ; )
Bottom Line... Roll Tide Roll... or for the next 364 days, Rule Tide Rule!
