The Charles M. Schulz Museum, in Santa Rosa, Calif., is celebrating one of the most popular "Peanuts" characters with an exhibition devoted to Woodstock, the little "hippie bird" who became a valued friend of Snoopy's. Luke Burbank talks with the comic strip artist's widow, Jean Schulz, exhibition curator Benjamin Clark, and cartoonist Paige Braddock, about the important role Woodstock played in the Peanuts universe.
