By Jonah Raskin | SONOMA COUNTY, California — As Austinites and their friends and comrades all across Texas know, the coasts, east and west, often get more media coverage than the heartland, and that part of the U.S. often described, unfortunately, as “fly over country.” Fly over it and much is missed. Dozens of books and films tell the story of Berkeley in the Sixties. Also, a great deal has been written about the many demonstrations that shook the nation’s capital to protest against segregation and the War in Vietnam. Not to explore and recount the movements that roiled towns and cities from Madison, Wisconsin to Austin, Texas, is to omit a crucial part of the story.
