Flags line the berm of the Veterans War Memorial in Seek, Coaldale. Today, Flag Day, commemorates the adoption of the flag of the United States, which happened through the resolution of the Second Continental Congress in 1777. In 1916, Woodrow Wilson, our 28th President, issued a proclamation that officially set June 14 as Flag Day. Later, in August of 1949, National Flag Day was officially established by an Act of Congress. Even though Flag Day is not an official federal holiday, Pennsylvania became the first (and only) state to celebrate it as a state holiday beginning in 1937 in the town of Rennerdale.
