I only went near Chicago one time back in '63. (a long time ago, evn before i was 39) I had occasion to close down my busines for 6 months and took a trip to the West Coast. On my way back to CT, the regulator quit in my truck. I could either waste some time searching the wilds of Idahoe and Montana for a new regulator, or take the lazy approach. I turned on every light anywhere on my truck to hopefully prevent burning up my battery, and kept driving. Early in the morning, i was proceeding past Chicago along a main route along Lake Michigan shore when I was pulled over by a friendly gendarme. He told me to stop and to stay put while he drove a couple hundred feet down the road. He told me to get out of my truck and to walk down to where he was waiting.
I had no idea what he was doing until he stopped me and told me to turn around. As I turned around to look at my we'll lite vehicle, he told me to take a good look. I was not sure what I was supposed to be looking at, excpt, at that point, my truck actually looked like a Christmas decoration. He said, and i did not take it as a question, "What the h--l is THAT!?!"
I explained my electrical problem and was told in no uncertain terms that the first thing I was to do was to turn off all of my lights and to get out of Chicago NOW. I did as told and breathed a sigh of relief to have been stopped by a cop with somewhat aparent sence of humor. Once down the road for about half an hour, i turned on all my lights, kept my fingers crossed until back home in Connecticut, where upon i got my electrical system repaired.
I don't recall that my sighting of Lake Michigan had been affected in any way by the deep blue @Dovetail65
that you are showing.
