Just a quick reminder that the Museum will be closed on Saturday, July 4.
Just this morning I was reading about when the first July 4th was celebrated. From Live Science:
The following year [after independence was declared], no member of Congress thought about commemorating the adoption of the Declaration of Independence until July 3 - one day too late. So the first organized elaborate celebration of independence occurred the following day: July 4, 1777, in Philadelphia.
