Chris Burden’s “The Big Wheel” at The Geffen Contemporary at MOCA.

While we’d like to think the Gold Line Eastside Extension opening is the center of the universe, there are other activities going on around Los Angeles this weekend.

One of them is just steps from the new Gold Line Little Tokyo/Arts District Station. On Sunday, Nov. 15 — the same day the Eastside Extension is offering free rides — MOCA (the Museum of Contemporary Art) is launching its largest ever exhibition to celebrate its 30th anniversary.

The show will be spread over two of MOCA’s three locations: the Geffen Contemporary (152 N. Central Ave., near the Little Tokyo/Arts District Station) and at  MOCA Grand Avenue (250 S. Grand, two blocks west of the Metro Red Line Civic Center Station). “Collection: MOCA’s First 30 Years,” will include more than 500 art works by more than 200 artists. It will run through May 3. Hours Sunday are 11 a.m. to 6 p.m. For more details.
