My parents were RVers, and spent one winter in the Spring Hill area, about 20 miles north of Tarpon Springs. I was still working, but I flew down on vacation one winter. We drove down to Tarpon Springs. Not only do they have Greek sponge divers, they have Greek restaurants. I'm not quite sure what I was eating and couldn't pronounce it anyway, but I ate myself into a coma. There was a dock on the lower level and the local boys would dive for coins that customers tossed into the water. No scuba gear. I have no idea how they could hold their breath that long.
