Regarding “Post Haste” by Robert L. O’Connell in your September/October issue: In the 1920s and 1930s my grandmother lived in a suburb of Chicago and we lived in a suburb of New York City. Letters to and from her were delivered overnight. Now my son lives in Midland, Texas, and I am on the eastern end of Long Island, New York, and letters to and from Midland take about four days! I fully believe one of the reasons for faster service between New York and Chicago back then was that the mail was sorted en route. Now mail is sorted on the ground in various central post offices.
