Open carry is generally illegal in Florida, but the folks pushing for more rights down there aren’t letting that stop them from holding some open carry rallies in the state. As it turns out, Florida law allows for some exceptions where open carry of a handgun is legal, and one of those exceptions is while fishing.
The open carry folks in Florida are taking full advantage of this, by organizing open carry fishing events in the state. Apparently this has been going on for some time, but this is the first I’ve heard of it.
