It wasn’t hard to pick out the Missourians participating, at least certain Missourians. An estimated 500,000 to 800,000 people from across the country joined the March for Women’s Lives on the National Mall in Washington, D.C. – the name given by pro-abortion rights groups protesting the policies of the Bush Administration. St. Louis march organizers distributed lime green T-shirts to many of the 2,000 Missourians who participated.
