Last weekend I was invited to what I would call a curated park cleanup: Show up, pick up tools or garbage bags, dial into a conference call, and learn a little about the park through earbuds while you pick up trash — no contact required. I went because the cleanup was held in South Los Angeles Wetlands Park, a place I had never heard of, at 5413 S. Avalon Blvd. As wetlands go, this one is a convincing imposter, described in a 2012 media account as “carved out from the industrial tundra of South Los Angeles.”
