Today's session of To The Best of our Knowledge interviewed a Californian who made it a personal pilgrimage to visit the sites associated with his states visionaries. The second part on maps was also very interesting since I have always enjoyed reading maps and they are a large part of my work.

Erik Davis, a fifth generation Californian, tells Jim Fleming that geographically and culturally, his state supports diversity and exploration. Davis is the author of “The Visionary State: A Journey Through California’s Spiritual Landscape.” The book features photographs by Michael Rauner, some of which can be seen at ttbook.org. Also, Peter Turchi is the author of “Maps of the Imagination: The Writer as Cartographer.” He tells Steve Paulson that both map-making and writing place great importance on the empty spaces.

I found it quite interesting that the first book begins with the ancient rock carvings that must have been created by visionaries. I want to make it out to China Lake sometime to go on the tour they have there.
