Didn't see the Lake Michigan lights myself but now I'm curious - did anyone manage to get photos or video? I'm out here in Nevada and we've been getting some strange sightings too, mostly over the desert around dusk. Last week there was something over the hills that I genuinely couldn't explain and I've been watching skies long enough to know the difference between a drone and something that moves wrong.
What direction were the lights moving? That's the thing that always matters most to me. Stationary lights could be anything but if they were doing that rapid shift thing, changing direction with no arc, that's when it gets interesting.
Also wondering if anyone checked the local news or flight radar at the time. I always do that first before jumping to conclusions, even if part of me is already hoping its something we can't explain lol.
