I was at Expo 67 with my family and we actually stayed a few nights at Habitat (experimental housing units) on the island. This was a cultural height of the mid century. Many art exhibits and people open to cultural exchange. At night the place glittered. I was so young it is hard to remember. We were happier then. At one exhibit we all looked at mirrors and a narrator told us that "the beast is man." I was too young to understand. There was very little fear and it was like a constant explosion of art.
