San Francisco's flower children, also called "hippies" by local newspaper columnist Herb Caen, adopted new styles of dress, experimented with psychedelic drugs, lived communally and developed a vibrant music scene. When people returned home from "The Summer of Love" these styles and behaviors spread quickly from San Francisco and Berkeley to many US and Canadian cities and European capitals. Some hippies formed communes to live as far outside of the established system as possible. This aspect of the counterculture rejected active political engagement with the mainstream and, following the dictate of Timothy Leary to "Turn on, tune in, drop out", hoped to change society by dropping out of it. Looking back on his own life (as a Harvard professor) prior to 1960, Leary interpreted it to have been that of "an anonymous institutional employee who drove to work each morning in a long line of commuter cars and drove home each night and drank martinis ... like several million middle-class, liberal, intellectual robots."
