Organizers at Summerfest in Milwaukee released a revised entry protocol policy Tuesday announcing that those attending the lakeside festival will need proof of vaccination or negative results from a COVID-19 test taken within 72 hours of attending. The Summerfest website says either a PCR or rapid test is acceptable.
The annual concert runs Sept. 2 to 4, 9 to 11, and 16 to 18. Last month, Lollapalooza, the giant music festival on Chicago's lakefront, put in place restrictions similar to those Summerfest announced.

Chicago's Pitchfork, which goes from Sept. 9 through 12 in Union Park, is requiring attendees either to show proof of vaccination or proof of a negative COVID test within the past 24 hours.
So concertgoers who are unvaccinated and attend multiple days will need to get tested daily, organizers said.
