July 1964. And 50 years ago a bus - a 1939 school bus, furnished with bunk beds, basic kitchen facilities and wired-up audio equipment - sets out from a house 15 miles from the Californian town of Palo Alto to journey across America. Painted in bright psychedelic colors with the destination sign of `Further` at the front and the words `Caution: Weird Load` at the rear, and carrying on board ten or so 60s` drop-outs from various walks of life, the bus makes its erratic way towards Route 60 and the road to New York.
