NATIONAL FRONTIER TRAILS CENTER Independence, Missouri. At the corner of Pacific and Osage stands the home of the National Frontier Trails Center, which doubles as the national headquarters of the Oregon-California Trails Association. This is an obligatory stop for anyone interested in the overland trails. In addition to a well-stocked library, permanent and rotating exhibits, and an extremely helpful staff, the Trails Center runs a good bookstore where you can view a preparatory film and purchase maps, contemporary and historical literature about the trails, and other useful guides.
