Hey David,
I'm sure you'll do alright, theres some good people down here and not many places where there is more respect for the next person. All you have to be is honest and play it forward, and you will fit right in and i do hope you'll enjoy the south. If you race and you are competative the racers will come to you and welcome you as long as you are friendly. I've been there and done that and i'm sure you'll love the climate/vs/snow and nasty winters.
