Has anyone here ever swam with a Dolphin?

They are wonderful creatures aren't they .. I have seen several TTV progranmes about them and they are so intelligent .. it does make you wonder what they could be capable of if only we could really understand them ... I would love to be able to touch a dolphin .. see if I could feel a rapport .. it's wonderful when you see severely disabled kiddies suddenly come alive when they are with dolphins ... really bring s a huge lump to my throat ...
