I'm at UF - and while Gainesville, FL isn't quite as Southern as you lovely ladies in Alabama, etc. we do pick up some of the aspects of the big Southern rushes.
All the sororities make "door decs" here too - we sneak in their dorms or go to their apts. late at night after they've all gone home after all the bid day activities. Then when they wake up the next morning, they have a surprise.

Some of the houses make their mascots out of big pieces of colored poster board, others make wooden door hangers.
Also, every new member gets a shirt on bid day and they all wear them on the first day of class. The fraternities have their new guys wear shirts too. So the campus looks like it's just totally invaded by Greeks! So fun.
