U.S. troops were sent to Vietnam in 1954 and, by the 1960s, thousands of soldiers had died fighting a war that was growing more and more unpopular by the day. The cry "Make Love, Not War" was a mantra among the hippies -- the antiestablishment, counterculture of America. Hippies were easily spotted: both men and women grew their hair long, wore ethnic-inspired clothes accessorized with puka shells, dabbled in Eastern religions, used words like groovy, and referred to "the Man" when talking about the flawed government. They were known to experiment with mind-altering drugs (marijuana, mushrooms, LSD) and hang out in places such as Greenwich Village in New York City and the Haight-Ashbury section of San Francisco. The hippie movement sparked music, art, and cultural dialogue that continues well into the 21st century.
