Im a bit curious where the line went if it was a mile long (or so they say).
Its a hell of a place. Haven't flown out of there for a bit though.
Im going to look for pictures...
Some pictures (yup its pretty long):
I like this quote: "The line for TSA at Midway airport leaves the terminal, goes to city train stop, turns around and goes back in. "
In case nobody knows where that is, that is the pathway to the CTA Orange line. You can see the CTA signs overhead.
