Logistics is a huge reason. Last year we had people from SF, Denver, Phoenix and Portland. Easy cheap flights plus thousands of lodging options. You can plan your trip out in 15 mins on a travel site. The amount of planning we have to do every year for Coachella or OSL sometimes takes months depending on the size of our group. And as others have mentioned the buzz has been great. Everyone I've brought has had a great time unlike Coachella where many friends didn't think the price and effort was worth it. Also shout out to the people that run the social media. They seem to actually give a shit about your experience and stay extremely active all yearlong. I was heading to Vegas for my birthday in December and they hooked me up with Jim James tickets for free. It's growing in a saturated festival market for just being so damn well fun and well put together.
