Getting your Trinity Audio player ready... We just spent a delightful week in Philadelphia and New York City with one of our grandsons. You see, we made a promise to each of our six grandchildren: Once they turn 10, we’ll take them anywhere in the United States they want to go. This year, two reached that milestone. One chose the Florida Keys so he could fish. The other wanted a completely different experience — a tour of two of America’s great cities. We gladly complied.
