John Hammond: You know the first attraction I ever built when I came down south from Scotland? It was a Flea Circus, Petticoat Lane. Really quite wonderful. We had a wee trapeze, and a merry-go... carousel and a seesaw. They all moved, motorized of course, but people would say they could see the fleas. "Oh, I see the fleas, mummy! Can't you see the fleas?" Clown fleas and high wire fleas and fleas on parade... But with this place, I wanted to show them something that wasn't an illusion. Something that was real, something that they could see and touch. An aim not devoid of merit.
