A golden rule of road trips is to never leave a building without using the bathroom. So, after touring the William J. Clinton Presidential Library in Little Rock, Arkansas, for two hours, I was waiting near the exit while my wife was in the ladies’ room. Suddenly, without fanfare, Bill Clinton strolled through a side entrance with a Starbucks coffee in one hand and the other waving. After I snapped the picture, shook his hand and exchanged greetings, he was gone. My wife missed the whole thing.
