There are some unusual objects that have been sunk purposely off of the Northeast Florida coast. “There are four press boxes from the Gator Bowl that are now out in the ocean 15 miles east of Mayport,” says Joe Kistel, TISIRI (Think It, Sink It, Reef It) executive director. “Scuba divers can even swim through the bathrooms.” Later this year, 100 tons of surplus concrete made up of bridge beams and other scraps from construction projects will be submersed about 12 miles east of Ponte Vedra Beach in an area called Floyd’s Folly. Tuff-E-Nuff, once the oldest tugboat on the East Coast is also now a reef. The boat was built in the 1890s, making it older than the Titanic. Not only are these reefs hard to find, but many times, companies or people that sponsor a reef ask for coins, letters and other sentimental items to be concealed on the reef. —K. F.
