Ditto to that.
One car in our group was over 10 hours late getting back to Illinois.
Turns out the driver, a Chicago native, took a wrong turn on I-44 heading west instead of east. He thought he was on the right road because he kept seeing mileage signs to 'Springfield' thinking they meant 'Springfield, Illinois'. I don't think he even knew there was a Springfield, Missouri.
Everyone else in the car was asleep.
The Chicagoan drove for 5 hours, INTO THE SETTING SUN.
He finally realized he had made a mistake when he saw the signs welcoming him to Oklahoma!!!! Needless to say, the other guys were really really pissed when he woke them up to give them the bad news.
