Participants in the wounded warrior soldier initiate the bicycle ride as they exit Andrews Air Force Base Md., on May 1, 2009. The wounded warriors rode from Andrews to Annapolis, Md., as a part of a four day event to raise awareness of issues that veterans are challenged with when they return wounded from the war and for many, the soldier ride provides an important step in their return to an active lifestyle.
