Today is 'swimming with dolphins day.' That is, I go on an excursion for this puprose. A boat takes us on a 40 minute cruise to a spot where dolphins are swimming. We jump out of boat, wearing a wet suit, snorkel and fins and hope that they don't just swim away. We're also told to make noises and swim around and around to attract the dolphin's attention.
In hindsight the making noises and swimming around made no difference, the doplhins swam around us - sometimes swimmining straight at us - and changed direction at the last second. They were within touching distance, but knew how to be just out of reach. It was an awesome experience. They are masters in the water and we splashed around hoping for their attention.
