I really enjoyed the DIA. At first, I thought it was kind of weird but after walking through the whole place, I really started to like it more and more. My favorite piece was North, East, South, West by Michael Heizer. From where we were standing on the side, we would have never known how deep they are. They are negative form pieces that Heizer did not even use tools to make. They looked like just holes in the ground but they it took a lot of thought to make.
