(SFGATE) — After the masses departed and the smoke cleared, workers descended Monday on Golden Gate Park to bag up and truck away all that was left behind by those who celebrated the pot holiday of 4/20 - an annual event that again tested the patience of some residents and city leaders.
While thousands enjoyed Sunday's informal smoke-out, police arrested 11 people around Sharon Meadow, and paramedics tended to four others. Traffic in the area was jammed all day. And officials estimated the cleanup cost would exceed last year's tab.
"Our goal is to provide clean, fun, safe parks, and there's a lot about this event that certainly isn't safe, and it's certainly not clean," said Phil Ginsburg, the general manager of the city park department, as he watched employees scoop up piles of trash.

"This meadow isn't designed for a crowd that size," he said. "Until every piece of trash is picked up, it won't be safe for people to play here."
