The TARS site at Horseshoe Cove, near the Florida Panhandle, is a former federal radar site, one of several that were constructed for the Tethered Aerostat Radar System (TARS) program, to monitor the southern border of the USA. At each site, a 200-foot long helium blimp, containing radar equipment, was connected to the ground by a two-mile long cord. Three of the sites along the Gulf were closed several years ago. Eight others, spread from Arizona to Florida, still operate. After this one was closed, it was sold to a company that built a warehouse and factory there, Gulf Coast Supply & Manufacturing, a sheet metal roofing and building company.
