The psychedelic bus that became a huge part of the hippie movement in America is to be restored for a planned documentary road trip. The vehicle, owned by writer Ken Kesey, featured at many peace and love gatherings throughout the late 1960s and 1970s and housed Kesey and hippie culture icons THE MERRY PRANKSTERS. The bus was made famous when it featured in Tom Wolfe's 1968 book THE ELECTRIC KOOL-AID ACID TEST. Kesey's son ZANE and his wife STEPHANIE are searching for a film deal and financial help to restore the broken down bus. Country star and environmentalist Willie Nelson has already offered to install a biodiesel engine in the vehicle, which has spent the past 15 years slowly sinking into a swamp in northern California. Kesey bought the school bus in the late 1930s with the money he made from his novel ONE FLEW OVER THE CUCKOO'S NEST and toured the country with his Merry Prankster friends.
