Having fly fished for red drum in the Santee and Cooper river estuaries many times I would thoroughly commend South Carolina to my UK colleagues. Furthermore, having spent many years visiting the Great Satan (work related) ,I Believe SC has the friendliest people in the US (although Brits may have a problem understanding them, particularly out in the boonies) And if the fishing wasn't enough, there used to be a bar that served Guinness and played the blues next to an Indian restaurant in Charleston - Heaven !!
(PS to any Brits - if they go crappy fishing - they really are going for fish. Oh and one other thing - if a girl asks you if you want to shag - she means do you want to dance - can lead to some interesting misconceptions - in all senses of the word!)
