With purple coastal mountains and the Bayshore Freeway in the background, the mechanical Aquatic weed harvester removes widgeon grass before it covers the lagoon, leaving a rotting oder after it flowers and the flowers die. Now the lagoon begins to glow again as it is cleaned up for the coming Berkeley Japanese Lantern Ceremony for World Peace, Saturday, August 9th, 6-9pm. It is a beautiful festival, introducing many to the wonders of Berkeley Aquatic Park, the worldwide harmonies of parklands, and the dark, deep memories of what happened in a world at war.
