Alright well just because you've been to Charlotte doesn't mean you know the city that well. How long were you there? Where did you go when you were there? Have you ever lived in or near Charlotte? I've lived in Gastonia which is right next door so I know the area quite well, and what it's like over there.Yes, both places mentioned.
I've also been to Detroit but that doesn't mean I know Detroit that well. When I was in Detroit it was only for a little while when I was at the airport when I was switching flights. You're certainly not going to learn much about a city when you're only there at the airport for the time it takes to switch flights.
