My Wife's McCain Sighting

My wife saw John McCain earlier today as he was leaving the Marriott. She reported that some folks were irritated that they were momentarily barred by police from proceeding on foot or by car as McCain and his entourage got into their motorcade and departed. I feel like she does - what is their problem? It's an honor to have this debate here, and it's silly to be put out because you had to stop briefly to let a presidential candidate move from one place to another. We've had several presidential visits to Nashville over the years where similar situations occurred. I don't think it's asking much of our so-called "Southern hospitality" to just smile and wave as the motorcade goes by.
