Things that go bump in the night are scary enough. Add in the element of an alligator-filled swamp and things that go bump on a boat, and you've got one of the most naturally terrifying situations we can imagine. Cypress Gardens' Halloween in the Swamp takes it one step further by having actors dressed as zombies hang out in said reptile-infested water to literally rock your boat. The swamp ride finds you dodging banyan trees as spooky ghouls pop out at you — and some really do try to climb aboard. You're then abandoned to make your way back to your car through zombies who want to eat your brains, or at least chase you and grab your shirt.
