A bridge, a bull and people’s opposing religious beliefs remain as obstacles. The Wall with Mexico proves less of an issue. It’s Episode 4, the final segment of the Lost Sea Expedition series. Join me this coming Thursday (January 28) on Rocky Mountain PBS (8pm), Amazon Prime and Vimeo as we finish our mule wagon voyage across America together. Plenty more videos, including trailers for all 4 episodes, are here on the Videos, Trailers and Extras page.
