The oldest one is now known as the Southern California Renaissance Festival. That is the one near LA that is done, I think, in the spring. The second oldest is the Minnesota Renaissance Festival, which started in 1972. That is where I am a performer. If people come out to the Minnesota show, find the Riddle Booth over by the Enchanted Garden and mention you saw this message on ENWorld. We'll make sure to give you a free riddle clue!I was told the earliest US RenFaires were in CA but I don't know how accurate that is. Does anyone here know?
