I do all that are listed and usually yell "Play Ball!" when the anthem finishes when attending a baseball game.
My one question is this calling of April 15th "Patriot Day". Is April 15th called Patriot Day only in Boston? I am almost certain that September 11th was reserved as "Patriot Day"for all of the USA. I thought April 15th was recently reserved for the TEA party (Taxed Enough Already)?
