The Rainbow Family Of Living Light with Barry "Plunker" Adams. A founding member of The Rainbow Family Barry, better know as Plunker, was part of the first Eugene Rennisance fair now known as the Oregon Country Fair. Not to mention Plunker was a judge at the original Cannabis Cup, receiving his name from a two-string instrument he plays at these various festivities. the Rainbow Family's full name is the Rainbow Family of Living Light, but you can just call them the Rainbow Family. Around since the early 1970s, this counter-culture group was heavily inspired by the famous 1969 Woodstock Festival as well as the anti-war, pro-love movements. Unlike many of the hippie groups that saturated the 1960s before fading away, the Rainbow Family lives on, holding annual Rainbow Gatherings.
