The last third of the story was filmed at Squaw Mountain Ranch, a family oriented nudist resort outside Estacada, Oregon. SMR was chosen due its location had been an old logging camp. The filmed needed a location with old cabins and RVs. Some of the members were used as extras in the "Birthday Party" scene. Squaw Mountain Ranch is the oldest nudist club west of the Mississippi and was established in 1933. They are open year round with rooms to rent in their lodge.
