Its just a cool name for the scene of a horror movie.
"Dont walk down Alligator Alley" (said in a scary over voice).
We have Crocodiles over here. They are nasty nasty nasty and not lazy. Them and Great White Sharks make a meal of a fair few tourists every year.
Why they dont read the signs that say "Crocodile Infested Waters" and take a moonlight dip is beyond me.
Then the poor bloody Croc gets turned into a pair of shoes, a purse and some mighty tasty steaks.
