I'm so extremely well prepared for negative response, I've taken precautions.

I've gotten all kinds of reactions and it's been used in so many different ways.

Dutch beaches were known to me as man-made territories, as part of various land reclamation projects. But I was also interested in the media reality of the Moon landing. I wanted to use that event as a measure of time, to see what had happened in those thirty years - which happens to be my lifetime as well. I was born in 1967 and I remember seeing the Moon landing on TV when I was two. All those things were in play. Then it became a big production. It took five months to gather up the goodwill and make it happen.

The Stonehenge proposal got a lot of interesting criticism. One of the best - or worst - said something like, "Go home to Las Vegas." I think this project could possibly be realized at a very late part of my career. Right now, I don't have the authority, the budget, the credibility.

I've made a poster at home. You know the iconic image of Che Guevara, the black and red graphic of his face? I think it's the perfect graphic, the best graphic ever made. I cut a Concorde out and put it over his head so it's Che looking up and the Concorde going by. Both are dead, maybe obsolete.

There are ends, occasionally, with projects. That happens. But they are natural dead ends. It's usually the outside situation that demands an ending. I never really settle for one.

I wanted to contribute to the landscape tradition in art. By now I guess we are comfortable with the thought that man has been everywhere or affected everything in nature.
