Boy, if I had a second chance, I'd be out looking to join a young bowling league, go swimming, play mini-golf or join a local gym during the time people my age usually go there. Entertainment parks are cool too.
I lived in Georgia and just loved the weather, city tours - don't miss Savannah or Atlanta - nothing like the old parts of town, and the seafood is just great. So, even if you don't need the money, find a part-time job where other kids your age work and get to meet new people that way.
Good luck, and enjoy the state - it has a lot to offer. Gosh, how I envey you!
