When July 4 rolls around, there’s no mistaking it. There are fireworks, parades and other patriotic tributes to our Declaration of Independence. If you’re like most Americans, Sept. 17 comes and goes without any fanfare. It’s a shame, really. Constitution Day may lack the flair and pageantry of our national birthday, but without this landmark document that carefully outlined the form of our republic, it’s unlikely we’d still be celebrating the declaration in the 21st century.
