Whats the strangest thing you've seen floating in the gulf?

I've seen bar be que pits, propane tanks. The coolest thing I ever saw was a giant manta ray. We were gigging flounder one night in about 10-12"s of water and the back of this thing was sticking out the water. My uncle picked up some sand and threw it at it and when that thing took off it made a wake like a crew boat!
