Worlds collide at the corner of Seventh and Market streets. Across the United Nations Plaza is a weekly farmers' market. Up the street is the futuristic Federal Building. On the corner there's a check-cashing joint and a Chinese takeout place. Above it all, behind the ornate terra-cotta decorations on the 1909 Odd Fellows Building, is the Alonzo King Lines Ballet Dance Center, home to thousands of dancers and this year celebrating its 20th anniversary.
