El Camino Real, Map App Man, Kickapoo Cavern

New awareness is being brought to a centuries-old pathway, the Camino Real de los Tejas. Meet a man on a mission to highlight its history as we trace a National Historic Trail through Texas. A new app helps Texas Game Wardens work with oyster harvesters to know where they can, and can't, legally harvest this delicacy. Birds, bats and caves are on display at Kickapoo Cavern State Park.
