We lived in Fullerton, very close.
Knots Berry Farm was free back then. Didn’t have theme park rides.
Had panning for gold. I wonder where those little vials with gold we had ever went?
Yep, the hippies loitering and crowding the place made them put up gates and start charging admission. Remember the stagecoach and the train where the “robbers” would board and have a shoot-out with the law? And Independence Hall?
