Several hundred veterans and supporters riding across the country on motorcycles passed through the metro-east late Tuesday morning.
The 26th annual Run for the Wall is from Rancho Cucamonga, California, to the Vietnam Veterans Memorial in Washington, D.C.
The ride honors prisoners of war and those missing in action.
The ride began Wednesday in California and will end Saturday in Washington, D.C.
The group stopped at Jefferson Barracks on Tuesday morning, left the hospital about 10:30 a.m., and made its way east from Interstate 255 to Interstate 64 and across the state.
