The information I have on Alan Sonfist isn't that pretty and candied coated.
I met him at an art symposium. He was a jerk. He was very late for
lectures and when he actual gave the lectures he was arogantand vage. He was
supposed to construct a earth work project for the symposium.....but he blew
it off and let all of his workers ( me included) waiting at the site for
him to show up.
I think your lesson idea is great I just felt the need to share my story
