Overnight, Memorial Park transformed from a booming concert scene to a barren — but clean — expanse of grass.
The patchwork of blankets, umbrellas and people that covered the lawn all day Friday were gone. And by Saturday morning, so too were the stage, the potties and the trash.
And even the stakes. Organizers had asked people not to use stakes to anchor blankets, but just to be sure that the ground was clear, about 10 people wielding metal detectors canvassed the park Saturday morning. They were there to remove any metal hazards as part of the cleanup process.
An estimated 74,000 people turned out for the concert Friday, headlined by Pat Benatar & Neil Giraldo and Loverboy.
Laura Mitchell, a spokesperson for Bank of the West, said the cleanup has become a speedy process. The bank has organized the event for the past 23 years.
By noon Saturday, only the green and orange plastic fencing that had looped the stage was left.
