Why at least five of the last six US presidents have come to one Western Maryland airport

Two days before he was to deliver the State of the Union address in Washington D.C., during an election year — a year in which he said “our very democracy” is “at risk” — an American president made an unplanned stop outside a rather unexpected locale: Hagerstown, Maryland. The airport for the city of less than 50,000 people, located about 20 miles north of the site of the Civil War’s bloodiest battle at Antietam, has been visited more times this year by President Joe Biden than the one for Baltimore, the state’s largest city that he toured by air in April.
