Calling all cool dads! Indio is, apparently, not just for waifish, flower-crown wearing, molly-tripping millennials. Who knew? Over the weekend, the first annual Desert Trip festival took place in California, more affectionately called "Oldchella." Put on by the same organizers as Coachella, the six-day, two-weekend event is truly a testament to #dadrock, those classic headliners you grew up listening to either with your parents or with your high school stoner boyfriend who still may or may not have a job. Bob Dylan, The Who, The Rolling Stones. Even Sir Paul and Roger Waters rocked out. From those familiar desert sunsets to a pig denouncing Donald Trump, click through for the must-see photos on the 'gram.
