CHICAGO - After four days of Lollapalooza, the festival grounds were due for a cleanup Monday in Grant Park.
Tents were being torn down and stages were being disassembled, but the streets surrounding the park including Jackson Drive, Columbus Drive and Balbo Avenue won't reopen until Thursday. Street sweepers and cleaning crews were hard at work, trying to get Grant Park back to normal.
Six years ago, damage from heavy downpour cost the festival promoter about $1 million.
The lost and found was very busy Monday with over 800 items left behind during the festival. Items included things like wallets and purses, keys, cellphones and even shoes. The lost and found is open Monday and Tuesday from 10 a.m. to 6 p.m.
When Blake Benfield lost his phone Saturday night, it was all he could think about.
"I gave up all hope, I assumed I was never getting it back and when a security guard answered it was the best relief of my life," said Benfield.
Benfield was reunited with his phone after a security guard found it, a huge relief before he headed back to Baltimore Monday night. He picked his phone up at Michigan Avenue and Balbo Avenue, where all the lost and found items can be claimed.
"If people are worried about their phone being lost then they can't focus on actual content of the event, which is what we want them to focus on," said Farid Mosher, the event manager.

Chicago officials say 27 people were arrested and 234 were taken to hospitals during this year's Lollapalooza music festival.
Melissa Stratton is spokeswoman for the city's Office of Emergency Management and Communications. She said Monday the arrests were for theft, battery and drug possession. Another 29 people were issued citations, most for jumping the fence around the festival and trespassing.
Police also said they detained a person Saturday who had 60 stolen cell phones. The person was released without charges because police said they couldn't obtain complaints from victims.
More than 100,000 people attend the event each day.
