Before jet planes and smartphones, merchants and pilgrims spent months traveling over perilous land and sea routes to carry luxury goods and new ideas thousands of miles across lost civilizations. Accompany the travelers over high mountain passes and parched deserts on their voyages of discovery and exchange. The event is free, thanks to the Friends of the Menlo Park Library, and it is located in the main library.
