Pot Lovers Flock to San Francisco for Annual 4/20 Smokeout

Thousands were expected to flock to Golden Gate Park on Wednesday, or 4/20, as the San Francisco’s weed-loving community call it, to celebrate being outside on the grass and the sweet smells (and effects) of cannabis. The exact spot in the park? Hippie Hill, of course. And the theme? A giant smoke-out. Bob Redell reports.
