Sweet Home Alabama

As part of my sabbatical, in April, I will be in Alabama at UAB as invited professor.
A breaking change for me. No kid, no wife for a whole month.
In one way, I will have time to do some research I had to delay due to lack of time. But in another way,
I worry to have too much free time :)

So where should I go, what should I see, what should I do during this month in Alabama ?
