If I wanted to learn hip-hop dancing, where should I go? I know all about the ballroom dancing studios, but I don't think they teach hip-hop dances.

For ballet dance lessons, I think Kentucky Ballet Theatre would be the best place to go. All ages are welcome, I'm pretty sure.
For swing dance lessons, try the UK Hepkats Swing Dance Club.
For ballroom dance lessons, come to the dance held by USA Dance every month because it starts with a free lesson.
