If anyone in our family wanted to step outside onto the Truman Balcony – the lovely arcing terrace that overlooked the South Lawn, and the only semiprivate outdoor space we had at the White House – we needed to first alert the Secret Service so that they could shut down the section of E Street that was in view of the balcony, clearing out the flocks of tourists who gathered outside the gates there at all hours of the day and night.
