Balding baby boomers, tie-dyed families and body-pierced teenagers gathered at the site of the original Woodstock concert Friday for a 29th anniversary show.

Far from repeating the crowded, chaotic atmosphere of the '69 show at Max Yasgur's farm, the three-day festival kicked off like a mellow, countercultural, all-ages show.Dads and kids swayed to the reggae sounds of the Melody Makers, bottled-water drinkers outnumbered pot smokers, and the concert staff gave parking directions to beige minivans instead of warnings about brown acid.

"It's a completely different scene," said Mike Feinstein. "We're grown-up hippies now. We have responsibilities."

One Woodstock tradition held true through: Evening rain fell on the crowd as headliner Stevie Nicks performed.
