I don’t know if the OP has chosen yet. There are no bad choices here, but I am most familiar with UNC. The businesses on Franklin seem to come and go; although quite a few have been there for many years. The new Target helps- I wasn’t thrilled with it at first but it blends in nicely. Is it as big as AA? No…but it’s a cute little town that merges with the campus and seems to serve the needs of the students. Older students seem to congregate in some establishments in CH, as well as Carrboro and nearby Durham.
Yes basketball is huge, but I would not call it a single minded obsession. There are a lot of other things going on including research ( it’s hard to find somebody who is not involved), strong academics, clubs with significant involvement, volunteering, acappella groups etc. So yes…basketball is huge…but it is really a piece of what students are involved in. It’s not the entire pie.
The OP has/had 3 great options. Good luck!
