A bunch of Dr. Bronners employees, if not management and ownereship, also active as part of the Southern California burner community. They show up at local festivals with sometimes the only public shower available -- its a huge, fully-nude group shower with a dance floor and a large, transparent plexiglass trailer, where they hose down like 100 people at a time from an overhead balcony. It's a lot of fun for anyone brave enough to bare it all!
It's funny -- they used to leave Dr. Bronners branding around (it was pretty subtle though) and were happy to let you try out their soaps, which is supposedly a faux pas in the burner crowd ... but they were so well-loved by the community that it was the only large camp that was allowed to get away with it. More recently the local burner festival banned any commercial expression, and they still showed up, completely revamped to remove any trace of Dr. Bronners, even if it was the same setup with the same soap.
TBH I am not the biggest fan of their soaps but I have an immense amount of respect for the company, as their presence and its contradictions really add to the overall vibe.
