In Dade County in Florida, (when I lived there that is, do not know about today) you could carry a pistol in a holster down the street, so long as it can be seen. No permit needed. If you want to conceal it, you had to have a carry permit.

Rifles could be carried in rear window of your truck, but in a car, it had to be in the trunk.
