CHICAGO (WLS) -- Lollapalooza continues in Grant Park Friday under strict COVID safety precautions.
Thousands of people flocked to Grant Park on Thursday as the four-day music festival got underway.
Friday night the festival tweeted that, following Chicago Department of Public Health guidelines and require masking at all indoor areas.
Organizers said that includes the merchandise store, two small hospitality lounges, the box office and wristband help tents.
The city defended their decision to allow the fest to go on, even though it may be a big risk.
Signs and announcements remind people they need to have proof of either full COVID vaccination or a negative COVID test result.
Unvaccinated guests must wear a mask, and pop up testing sites are all around the perimeter.
"It's easy enough for everyone to go get tested they were offering it right down the street, it's easy enough for everyone to get vaccinated if they feel comfortable and so I feel like it was appropriate, it's not keeping anyone out unless they have COVID which I think is fair," said attendee Reagan Tallmadge.
The city hoped this would be a safe celebration but case numbers in Chicago are creeping up.
Lolla organizers tweeted Thursday that more than 90% of people showed proof of vaccination, 8% brought negative COVID tests and 600 people didn't bring paperwork and were not allowed in.
COVID tests shown by unvaccinated attendees cannot be more than 72 hours old, so anyone with a four day pass that isn't vaccinated has to get tested twice.
