Hearing strange booming sounds in the northwest side of Chicago. The sounds started this morning and still going. It sounds like thunder or fireworks or even like bombing from far off. My cousin who lives in Elgin Illinois heard two big booms then it ended. Does anybody know what this could be?
Here an answer to this message from Facebook:
Hearing these sounds all night too by north side of Chicago…, I’m perplexed as well
