I'm trying to figure out how a music festival could operate at Big Sur. Wikipedia says the Big Sur Folk Festival was held from 1964-71. It was held at the Esalen Institute, and accommodated crowds of 3,000 to 6,000 people. That seems to be a lot of people to accommodate on the Big Sur Highway (Highway 1).
In October, 1970, it was held at the Monterey County Fairgrounds. That was a 10-minute walk from the apartment where I lived from June to October, 1971. I don't think I even knew about the Big Sur Folk Festival at the time. We stayed away from the festivals at the fairgrounds because they were just too crowded.
