The Chapel Hill Flying Club is actually in Sanford, which is bit of haul down 15-501. There is a club in Durham (they're in the yellow pages) which is very close-knit, I just can't recall the name right now. They have a fly-in once per month and everyone I've met from there was VERY friendly and easy-going (as you probably know ... this ain't always the case with flight schools). I will look up the info if you want.
There is also Southern Jet at RDU which is now run by Margeret Riddle, who's been around the local flying scene since Jesus was a baby. She's a little 'stern' but is a wonderful instrument instructor.
There's alot of GA in the area ... PM if you need specifics.
