Flag Day was established in 1916 to honor the day the US adopted its first flag, June 14, 1977. I found some fun websites about flag day with all kinds of great facts about the flag. The best website I saw today was http://applications.appleton.org/parades/flagday%202012/ . Appleton is where we are going to move someday and I love that they make such a big deal for flag day. Someday I will see the parade in person.
