Run for the Wall
A participant in the "Run for the Wall" acts as a road guard, directing the riders where to go as they pass through O'Fallon, Ill. May 22, 2012. More than 1000 people participated in this year's 2600 mile, 10-day road trip across the country. Starting in California and ending in Washington D.C., the mission of RFTW is to honor all service members past, present and those who were declared missing in action or prisoners of war.
