"From time-to-time this writer marches up and down the mall carrying a picket sign protesting against such things as the Iraq War and the killing of seventeen-year old unarmed Trayvon Martin by George Zimmerman, or protesting for Health Care for all, what some people call "Obamacare." (Let me add, Obama cares a lot.) Usually while protesting I sing and give my voice to the cause I am protesting. At other times I play the harmonica and/or sing to entertain or lift the spirits of people who often give me thumbs up." More here.
