Nan,
Like I said before, I'm 21 and have lived in Charlotte since 2000. Just went through this process three years ago so I remember it very well.
A couple other schools worth looking at (if youre looking for a safety school) would be ECU, APP, and UNC-Charlotte, although those are all a lot bigger sized student bodies than what you'll get at HPU, Elon, and Wake Forest.
One school I would HIGHLY suggest looking at for your son is Washington and Lee University in Virginia. It is like Wake Forest on steroids. Campus is GORGEOUS and is about 2000 kids. Very good academic school.
Don't mean to bore you/guide you in one direction or another but if you or your son wants any other opinion on schools down here DM me and i'll give you my email. Hope I can help.
