We're dusting off our old documentary photography boots and traveling back to 1969 this weekend. We're covering Desert Trip (a one of a kind music festival in the Coachella Valley with The Rolling Stones, Bob Dylan, Paul McCartney, Neil Young, the Who and Roger Waters of Pink Floyd). We're looking for the best characters in the crowd for @aarpphoto and shaking a leg with them. Follow along the next three days to see what we see!
