A distinctive 1939 school bus, famously painted in psychedelic colors during the height of San Francisco’s 1960s counterculture movement, has returned to the city for public display after more than five decades. The bus, known as “Furthur,” was recently transported from the Kesey family farm near Eugene, Oregon, to Golden Gate Park, where it will be featured in an exhibit beginning September 5.

The bus gained notoriety as the centerpiece of the Merry Pranksters’ cross-country journey promoting the era's ethos of free love, expanded consciousness, and resistance to societal norms. Painted in swirling Day-Glo hues, the vehicle was owned by Ken Kesey, author of the novel “One Flew Over the Cuckoo’s Nest,” and served as a mobile symbol of the 1960s counterculture. Its name “Furthur” appeared misspelled above the windshield, and a sign on the back read “Caution: Weird Load.” The Pranksters outfitted the bus with beds, benches, a powerful sound system, and a rooftop balcony.

The journey of the bus was later chronicled in Tom Wolfe’s 1968 book, “The Electric Kool-Aid Acid Test,” and the vehicle itself became intertwined with San Francisco’s key cultural events, such as the 1967 Human Be-In gathering in Golden Gate Park—a precursor to the famed Summer of Love. The bus was also immortalized in music references, including the Grateful Dead’s song “The Other One,” which mentions Neal Cassady, the Prankster’s driver.

Over the years, the bus weathered neglect and deterioration while resting on the Kesey family’s property. Zane Kesey, Ken Kesey’s son, along with his wife Stephanie Kesey, arranged for its transport from Pleasant Hill, Oregon, to San Francisco for the exhibition, part of “Forever Grateful, Golden Gate Park,” organized by the Haight Street Art Center. The show seeks to preserve and present key artifacts and stories from the city’s countercultural past and includes other exhibits such as Jerry Garcia’s BMW and live performances.

Kelly Harris, executive director of the Haight Street Art Center, described the bus as still possessing a “magical and connective” energy despite its worn appearance. Roger McNamee, chairman of the center’s board, called the bus “the Rosetta stone of San Francisco’s counterculture” and emphasized its relevance in today’s context of technological dominance and social conformity. He suggested that reflecting on the bus and its symbolism could inspire greater happiness and resistance to societal pressures.

Zane Kesey, who grew up around the bus and helped paint it as a child, spoke of it affectionately, referring to the vehicle as if it had its own personality. He acknowledged the significance of returning the bus to its cultural roots in San Francisco, hoping it would rekindle some of the spirit of exploration, peace, and kindness the era represented.

Following the exhibit, the bus is slated for storage in a warehouse in the East Bay associated with the Burning Man festival, while fundraising efforts continue to restore the vehicle and eventually house it permanently in San Francisco. According to Stephanie Kesey, the family does not anticipate the bus returning to the Oregon farm.

The bus remains a potent symbol of a period marked by social upheaval and cultural experimentation and now serves as a historic reminder amid ongoing national debates on war, politics, and cultural values.
