When World on Wheels reopened in 2017 after a four-year closure, a line of eager skaters wrapped around the building, custom skates and rollerblades clenched in their arms. The beloved Mid-City skating rink was more than just a place to lace up and glide. It was a cultural institution — part of Los Angeles’ early hip-hop scene and a safe haven for youths who came from rival neighborhoods in South Los Angeles. Skaters looked to this rink variously as date destination, fitness facility, daycare center, therapist office or family room. Thanks to an enthusiastic entrepreneur who won the support of rapper, community activist and local hero Nipsey Hussle, the rink received a much-needed face-lift that drew fans back to the hardwood floor.
