FWIW I just completed my CCW class last weekend. According to the instructor there are only two states you can legally "open carry".....Arizona and Alaska.
Florida is not an OC state but for the vehicle we do not need a CCP, no restriction as to where it may be carried nor condition of ready with the exceptions that it may not be concealed on the person without a permit nor in view of the passerby. It may be on any floorboard or in any storage compartment in any state of ready.
