Even as the hippies of Woodstock become eligible for AARP cards and Social Security, tourists still flock to the former hay field where a concert 35 years ago helped define a generation. Today marks its anniversary. The steady dribble of nostalgic baby boomers and curious Gen-Xers to the remote field shows how Woodstock still reverberates in the popular imagination. The concert remains a symbol to many of the transcendent power of music. The Woodstock story is well known: rock promoters fail to land the lefty arts colony of Woodstock for a festival site and settle on a dairy farm about 50 miles southwest in Bethel. Some 400-thousand people show up and by the time the weekend of rain, mud and blissful anarchy was over, Woodstock had became an icon of hedonism, anti-war sentiment and youth culture.
