Woodstock: los hippies vuelven a Bethel 50 años después

In this undated photo, people rest at the campground of the Woodstock Music Festival during the week-end of August 15 to 18, 1969 in Bethel near Woodstock. - Hundreds of thousands of people peacefully communing for a weekend of music, free love and mind-expanding drugs -- in today's era of mass shootings, the popular free-wheeling image of Woodstock can seem a bit naive. Major events in America now are not complete without metal detectors, bomb-sniffing dogs, bag inspections -- and the ever-growing paranoia that a gunman could be in the crowd. And law enforcement officials say the chances of a Woodstock-like gathering ever organically springing up again are slim.
