NPCA introduces its new Park Stories podcast series by taking you into Yosemite National Park for an engaging encounter with one of the park's first rangers, Sergeant Alizy Bowman, a member of an African-American regiment of the U.S. Army that stood guard over Yosemite well before the creation of the National Park Service. Bowman was a Buffalo Soldier, and his inspiring story is shared by Park Service Ranger Shelton Johnson.
