Years ago, I interviewed a man named Dr. Stephen P. Leatherman, a professor and the director of the Laboratory for Coastal Research at Florida International University. I was writing an article on Tampa Bay’s best beaches, and wanted to know how the man known as “Dr. Beach” chose his ten top American beaches each year. He went into specifics about beach conditions, sand softness and color, the presence of wildlife, the views, water temperature, safety. He actually had a list of 50 criterion.
