So I returned to D.C. for the Tax March on April 15 held on the West Lawn of the U.S. Capitol. Here's a an explanation from the movement's web site:
"Tax March is a growing national movement that extends far beyond one day of marching. Led by everyday Americans who are tired of paying into a system that is rigged in favor of the super-rich, the Tax March movement maintains that any reform to the tax code should be about closing loopholes for the wealthy and big corporations and building an economy that invests in working families.
