Oh lordy, I live in Florida where we are swarmed be tourists! I could probably rant on for pages about the annoying things them do.
First off, don't talk about how much better whatever is where you came from. If it's so much freaking better, go back there!
Don't make fun of the way we talk. Yep, we have a Southern accent because WE LIVE IN THE SOUTH!!!
Leave the wildlife alone! Don't try to pet or take a selfies with gators, manatees, dolphins or other critters.
