Things got off to a delayed start Friday at Lightning in a Bottle music festival, as overnight rain pushed back the event's start time to mid-afternoon. It picked up significantly from there, however, and figures to remain that way through the remainder of the weekend at Buena Vista Recreational Aquatic Area. A total of 20,000 attendees are expected to attend through the weekend, with the vast majority expected to camp on festival grounds. While the event — which lasts through Monday — will feature well-established electronic music acts as well as up-and-coming artists, music is just part of the experience. From yoga to art installations to educational seminars to food vendors, organizers attempt top pack as much as it can into the festival area. Check back throughout today for updated photos.
