Sorry for the delay; I (sadly) had to travel back home yesterday and just now saw these. Geo - no Oakleys in what we found. Luvthebeach - we were within a mile of 1 Seagrove and 3 of these were black, inexpensive retail brands (1 doesn't even show a name brand anywhere). Did yours have a brand name or perhaps a unique design "pattern"? Based on other debris we found including many beer cans, we think an inflatable "party barge" got flipped over somewhere, maybe as far as Cozumel or Key West based on all of the seaweed wrapped around some of the items.
