The Purple Heart Trail was established in 1992 by the Military Order of the Purple Heart to be a symbolic trail throughout all 50 states to commemorate and honor all men and women who have been wounded or killed in combat while serving in the U.S. armed forces. The Purple Heart Trail originates in Mount Vernon, Va., and traverses the United States to California. More than 20 states have implemented the trail, including Hawaii. The trail has also been implemented in Puerto Rico and Guam.
