Ughh... forgot about the bones in the feet dealio. That sucked. Pretty sure those were burrs off of burrfish. Shaped perfectly (triangular/pyramid) for getting you every time. Sharp, hard and tough.
I just realized when you mentioned the dead redfish that Gordon put that in his Hurricane Dennis video (2005) so that was the date. The fish are at 1:30.
Billy was just learning to do his first handle passes then, as well.
Oh, the kites really sucked, I remember that too.
