From Ammoland:

GOA and Hughes sued State Attorney Thomas Bakkedahl and St Lucie County Sherriff Keith Pearson over the state’s ban on the open carrying of firearms. Florida law bans the practice unless the carrier is engaged in the act of hunting or fishing. All other citizens open carrying a firearm are subject to arrest. Florida is one of the only states in the country not to allow the open carrying of guns. The plaintiffs in the case believe the law is unconstitutional and violates the Second Amendment.
