I'd heard about them, but I didn't believe.
Stuck at Midway for 3 hours, even the hot dogs are the friggin airport are dah bomb. Char-grilled, piled high with peppers, onions, etc.

Yes, I lived almost 50 years without having one, and this is not my first trip to Chicago, though it has been a while (20-odd years). I don't know what was wrong with me before.
