Florida drivers, thought you would like to know this tidbit from a local boy. To my knowledge this does not apply to plates from ANY other state; it is specific only to cars with Florida plates.
I live in Sylva (about an hour West of Asheville, North Carolina). The geographic location is in the Southern Appalachians, North of Georgia and South Carolina and East of Tennessee. This would include the cities of Sylva, Highlands, Cashiers, Cherokee, Bryson City, Murphy, Waynesville, etc. Once you get as far East as Asheville this advice no longer applies.
The townsfolk in this area DO NOT LIKE Florida drivers, nor do police. In this circumstance they really are out to get you. Now if you switch to North Carolina plates suddenly everyone is your friend and the cops don't hassle you.
This mindset is a really odd phenomena that I noticed among the locals after moving here a number of years ago. Just thought you'd find this useful when planning a vacation to the area as I know you like our mountains.
