Three-time Pulitzer Prize-winner Paul Conrad was the LA Times' political cartoonist for many years. In 1991, he designed a sculpture made of tangled chains that formed a mushroom cloud as a warning against the horrors of nuclear war. Since 1991, "Chain Reaction," has been a fixture outside City Hall in Santa Monica, but it became so deteriorated that the City Council approved its removal as a safety measure. Then it was designated a local landmark, and there's been a campaign to save it. Tonight, Bob Scheer will be part of a fundraiser at Writer's BootCamp at Bergamont Station. He's editor in chief of the website TruthDig and a featured presence on KCRW's syndicated program, Left, Right and Center.
