 It happened a couple more times. Probably the longest trip that ever occurred from a child being mailed was from a six-year-old named Edna Neff. She traveled from her mother's home in Pensacola, Florida, to her father's home in Christianburg, Virginia, which is a little over 700 miles. Went by railway mail train. Cost 15 cents and parcel post stamps, which is much cheaper than a train ticket going from Florida to Virginia.
