Didn't see it myself but I've got a mate in Kenosha who messaged me about something odd that Thursday night - he's not into any of this stuff normally which is what made me take notice. He said it was maybe five or six lights in a loose triangular-ish shape just sitting there for a good few minutes before they split off in different directions.
Question for anyone who did witness it - did the lights appear to pulse or change colour at any point, or were they steady? And was there any sound at all? My mate said completely silent but he was watching from inside so I'm not sure how reliable that is. Trying to piece together whether this matches anything on record from that area because Lake Michigan has a surprisingly consistent history of sightings going back decades that dont get nearly enough attention.
