Michael Fritton ,Lord Landcrab, tells a tale of a dolphin he met in Brewer's Bay while swimming. The dolphin started performing tricks and jumping over him..Fritton thought he was a natural genius til some guys in a boat pulled up to hunt down the dolphin who had escaped from captivity. Hopefully the dolphin got away. So, while I believe dolphins dont forget how to interplay with humans I think they are much happier doing it in their own environment not in some stinking pool. I was lucky enough to witness two dolphins playing with kids in The Bight on Norman and it was magical to watch. When they had had enough they just swam away..
