best day of my life but....

Last month I was accepted on Early decision and today everything was finalized with finances and my parents. I will be at Columbia this fall, a dream I've had since first visiting NYC on a field trip in 7th grade. The thing is I'm from South (Atlanta). I'm not at all what the rest of the country thinks of southern girls. I just want to know if this would count against me? Also recs are very important here but I don't have connections in the majority of your organizations. Any advice would be wonderful.
