This Monday (11/11) is Veterans Day. It’s also my parents’ anniversary, they were married in 1951. At that time the holiday was known as Armistice Day, commemorating the end of WW1 (then called the Great War, these were not numbered until the second one). They chose this day so they would have their anniversary on a holiday.
Some history of this holiday here.
In Prescott the parade is downtown as always, 10:30 to 1 PM. Details here.
