I've lived in Florida my whole life. I've seen more gators than I could even count, and I'm generally not afraid of them (I've also eaten a lot of gator in my day, and I have a strict policy of not being afraid of my food). 

This South Carolina came home to find a gator on the second floor of their porch. SECOND FLOOR. That means these things can climb stairs??!! 

NOPE.
