Investigations have begun on the Mullet Key Bombing and Gunnery Range Formerly Used Defense Site, now known as Fort DeSoto County Park on Tampa Bay. Soon after the Labor Day holiday, contractors for the U.S. Army Corps of Engineers began surveying the site to mark the areas for investigation, which will then be cleared of brush and swept with digital metal detectors to identify buried metallic objects that may potentially be munitions remaining from past military activities.
