I grew up near Birmingham, AL. I imagine the football thing is a big part of the reason for that particular Google search. In fact, if you have any questions about Alabama, football is likely the answer.
Still, having lived in Georgia, having my sister and mom in Mississippi, and dipped my toe in Florida a couple of times, I'd say why is Alabama so good is a pretty good question considering the other places. Everytime I go through lush, impoverished Mississippi I think, "Why is it so darn poor here?" and everytime I am in Georgia i think, "Why is this land so ugly?" and when I am in Alabama I think, "Alabama the Beautiful!" damn straight!
