Although I agree with the your general statement about fixing Open carry in Florida, this specific point is well settled case law and has already been "fixed" by several appellate court decisions. One's "home" includes inside as well as on the property surrounding the house plus any outbuildings that are part of that property. It also includes inside your hotel room, apartment, etc, but not the common areas like hallways/parking lots. It also includes your parked motor-home, tent, or any other temporary lodging. If in a condo or other type facility like duplex, or mobile home parks, it would also include any property, designated for your exclusive use, included in rental/lease agreement.
I was not aware that this had already been resolved in the Florida courts. Thanks.
