On the day I graduated from college, my sister was on a trip in the same state with her high school class. She wanted to celebrate with me and—fortunately—a chaperone was willing to drive her 6.5 hours north to my school. But as they drove away from the hotel, they headed south. Obviously, neither of them had a strong inner compass. For it was several hours later—after they entered a scenic area deep in the southern region of the state—that they knew something was amiss.
