20060811 Mooring Buoys 3 of 6 — Photo by John J. Lopinot / The Palm Beach Post — Carlton E. Oakes (CQ) of Aqua-Terra, Inc., of Hobe Sound, uses a special drill to make a hole for a stainless steel pin that will be used to anchor mooring buoys at St. Lucie Inlet Preserve State Park. Aqua-Terra has the contract to install and maintain mooring buoys and park boundary buoys. After Oakes drills the hole, he installs a stainless steel pin and anchors it with expoxy. 24 hours later, after the epoxy sets, the pin is ready for a rope and buoy to be attached.
