It will be more beneficial for you if you give more criteria than just an hour from a beach and not infected with racism. So you want to leave SC? East coast....west coast? What kind of job opportunities are you and your sons after etc etc. This will be helpful in offering the best advice
P.S. when I was stationed down in SC about 10 years ago we were actually restricted from going to certain establishments off base cause the owners of said establishments were racist...crazy and sad this crap still exists. Hope you find somewhere you and your sons love and can live happily and not have to deal with that.
