I googled this – it’s a place in the Keys where you can get a catamaran out to the Dry Tortugas. It sounds like fun!
I did google to see if shelling is permitted on Dry Tortugas. Apparently, if it’s on the beach and unoccupied, you can have it. But if it is in the water, you must not disturb it.
Not sure this is really a memo. Except it does sound like a cool weekend trip. There’s a "taxi" out of Fort Myers down to the Keys – I hear it only takes a couple of hours to get there by boat.
