There was a weekly freestyle dance in New York City that I attended, many years ago. In a studio, with a good wood floor, near Broadway and Houston. It was run by a collective, and part of a northeast association, which had summer dance camps. As I recall, it cost $5 at the door, and less if you subscribed. All ages were welcome, even toddlers. Maybe it still exists. And there are many others, for different dance styles.
