Ken Kesey's original "Furthur" bus on its latest trek

In 1964 Ken Kesey and his “Merry Pranksters” rode a bus named “Furthur,” fueled by music, alcohol and LSD. This icon of the counterculture movement, which has fallen into a rusted state, is now on display in San Francisco, on a journey to restore it to its former glory.

In 1964 Ken Kesey and his "Merry Pranksters" rode a bus named "Furthur," fueled by music, alcohol and LSD. This icon of the counterculture movement, which has fallen into a rusted state, is now on display in San Francisco, on a journey to restore it to its former glory. It's some 37 feet of rusted steel, peeling paint, and shattered glass. But even at rest, this 1939 International Harvester school bus, called "Furthur," conjures a sense of motion. "Furthur really is a call to action," said Kelly Harris, director of the Haight Street Art Center in San Francisco. "It reminds us to never stop creating, never stop exploring, and keep pushing further." The bus is the centerpiece of an ongoing exhibit, "Forever Grateful," that celebrates the countercultural revolution that bloomed in Furthur's wake.

"I do believe that Furthur is meant to go further," Harris said. "So, the journey is just beginning. And there should be an opportunity for generations to feel inspired by the bus." The man behind the bus was author Ken Kesey. In the early 1960s, as a Stanford creative writing student, Kesey was a willing test subject for U.S. government experiments using LSD.
