This augmented reality experience recreates John Burns joining Union soldiers in the fighting at Gettysburg on July 1, 1863. The 69-year-old Gettysburg resident grabbed his old musket and powder horn and headed toward the fighting, eventually reaching the 150th Pennsylvania Infantry. Burns was sent into the woods next to the McPherson Farm, where he fought beside the Iron Brigade, first with the 7th Wisconsin Infantry and then with the 24th Michigan.
