Got back from the Big Island of Hawaii. Not quite ready to come back. Not thinking in full sentences yet. One of the highlights of the trip was scuba diving at night with enormous manta rays. I can't think of anything to compare it to, except maybe a primordial liquidy circus ballet. At sunset the dive boat takes you out to a particular cove near the Kona Airport, where, for some reason, the plankton is especially prolific. The mantas need to ingest tons of plankton every day, and seem to appreciate the light that divers bring with them. And the divers get a wonderfully reliable show almost every night. The dive procedure is incredibly simple. Just descend about 30 feet, kneel on the ocean floor, and shine your light upward. The mantas will swoop and undulate just inches from your head, hungry for all the plankton that you are illuminating!
