A modified American flag flies during a show Saturday celebrating the 29th anniversary of the Woodstock concert. "I can't relate too heavily to the original scene, obviously, but it's a real cool place to see a concert," said 22-year-old Justin Garrett. "Everyone is chilled." Woodstock veterans Pete Townsend and Richie Havens performed Saturday, along with Joni Mitchell. The festival runs through today, which is reserved for younger acts like Third Eye Blind and Goo Goo Dolls.
