Is SC or GA more car hobby friendly?

If you and your family have the right mindset, you will fit in fine. Just remember there is Atlanta and the "rest" of the state. Also realize the Civil War never really ended, just delayed awhile due to lack of cannon balls and grits!! Also be advised the South moves a little slower ( except Atlanta) and marches to the beat of its own drum.
I was raised in rural SW Ga farming county. I mean very rural. I moved to Missouri in '79 at age 31 and lived there for 37 years before coming to Tx. . It was a border state so being from the South I did well living in SW Mo but was on the line in NW Mo. but I adapted. Only once did a guy want to whip my *** for being Southern.
