FL. Siesta Beach on Siesta key Named Best Beach in United States

[Dr. Beach, aka Dr. Stephen P. Leatherman, Director of Florida International University's Laboratory for Coastal Research, releases his Top 10 Beach List before Memorial Day each year. Siesta Beach, on Siesta Key, a barrier island southwest of Sarasota, has been playing bridesmaid for two years now, but earned top honors in this, the 21st year of Dr. Beach's rankings.

"Siesta Beach in Sarasota boasts that it has the finest and whitest sand in the world, and I cannot argue with this claim," Leatherman said of this year's winner. "The powdery sand is nearly pure quartz crystal. The beatiful blue-colored water is clean and clear, making it so inviting to bathers and swimmers."]
