That having been said, some of the best Dance programs in the country are at North Carolina School of the Arts, Butler University, (Indianapolis, IN), and University of Utah (for Ballet). Sara Lawrence College has a great program if you're interested in choreography, and they're 30 minutes from NYC, giving you ample opportunity to come take class in the City and audition, as well.
Knowing what specific genre you're interested in would be helpful in giving you more guidance for this.
Start by looking at companies you want to dance with or dancers whose technique you aspire to. Find out where they studied. I think that's a great stepping off point.
