At more than 4,500 acres, Griffith Park is one of the largest municipal parks in the United States. Its founder, the controversial and complicated Griffith J. Griffith, donated the land to the city as a public recreation ground for all the people — an ideal that has been challenged over the years. In this episode, Sarah Wilson, director of Education at the Autry Museum of the American West, explains the upcoming “Investigating Griffith Park,” exhibition and the effort to create an archive of all things Griffith Park. It also features Casey Schreiner, hiker and author of the book “Discovering Griffith Park: A Local's Guide,” in a visit to a Mexican-era adobe within the park boundaries. We also ride the historic Merry-go-Round where Griffith’s ideal of equal access was challenged.
