Just a strange rumble that would be headed towards Chicago. Not a jet sound. Camping so we're outside cooking dinner.

I live near a base and boat of planes are going East and they definitely don't sound like your regular Boeing 747s. The sound like military, had a few helicopters platoons too. Like, 4 to 5 in a row.
