I can confirm this dude’s statement about caimans. I used to hang out in their neck of the woods a looong time ago when I was a teenager. A few minutes away from Key Biscayne is a little tract of federal land where an old squatter named Jimbo built himself a little shanty town in a cove. He’d sell smoked fish and if you left cash on a counter, you could grab canned beer from a nearby cooler. My friend and I would see all kinds of wildlife in the nearby trails and water, usually gators, deer, and manatees. A few times we did see caimans, and they were always the most hostile fuckers. We called them Meth Gators.
