The skinny dip was part of the Rhythm and Vines music festival each year.
Starting in 2012, it was part of the BW Summer Festival, which helped host the visitors of R&V in the campgrounds (not as part of R&V directly).
Unfortunately in 2014, a riot broke out at this in the campground, some campers decided to set tents on fire and started fighting and throwing things at each other resulting in 68 arrests and 83 injuries.
Rhythm and Vines took over the campgrounds in future years and there has been no sign of the skinny dip ever since. A huge loss as there seemed to be a decent turnout (especially woman) and great footage turned up each year from a local videographer.
