In May 1947, the month I turned 13, I came close to meeting President Truman. Represented Florida in the National Spelling Bee, and he was scheduled to receive us, but his mother was ill and he had to fly to Independence to be with her.
Did go to the White House, though, but not through it, that being renovated at the time, and much of Washington on tours - Mount Vernon by bus - back on a paddle wheeler on the Potomac.
