I have not been aware of Constitution Day, but I am glad we have one! The United States Constitution, established in 1787, has served me well. I am thankful to be an American.
September 17 has only been designated Constitution Day since 2005, but social media is helping it catch on. Also, higher education institutions that receive Federal funds are expected to acknowledge Constitution Day.
So cheers for freedoms given by God, defined by the Constitution, defended by the military, upheld by the judicial system, and celebrated by the people.
