I'm from near Research Triangle Park in NC and have to say that the weather is miserable all summer, just horrible. The traffic is abysmal, and everything is strip malls and McMansions. You can top that off with the insane gerrymandering in NC that prevents the most populace areas from having any political power. Locals are quite hostile to new-comers, and the government keeps trying to tell people which bathrooms to use which is just bizarre. Yeah, BBQ is great, the schools are good, and low taxes are nice, but NC really misses the mark for me in a lot of ways. Having grown up in the area, I am not a fan.

I don't know too much about the other places.
