Diamondback rattlers swimming the magroves?
I went to visit a rental I have today and the tenants advised they had taken a charter out back behind Cudjoe Key through Bow Channel. I don't know exactly where they went but they were adjacent to one of the mangrove keys back there and caught some sharks and a bonefish. A pretty good size rattlesnake like maybe 3' long swam up to their boat and was looking to climb their anchor rope. They showed me some photos of it next to the boat. Definitely not BS. Their guide was shocked and I was pretty taken aback myself. I have never seen a snake back there or a croc for that matter. Anyone ever see any rattlesnakes in the back country?
