People should go to the works and experience them. Because just having an idea or picture in mind is absolutely not the experience that's necessary. Even just landing in Albuquerque or Salt Lake City or Las Vegas was immediately part of the experience. And then you'd get in a car from the airport and take these very long trips - in Michael Heizer's case, it was three hours by car to get to his work. And then there's walking around and into the piece and seeing it from different angles. The kinetic experience of being a part of it physically was very important for me.

People tend to view land art as something that happened at a certain historical moment - like minimal art, which I was also very much involved with. But it still goes on. It's very much alive.

Making the effort is quite a pleasure in itself.

I think Michael Heizer and Walter De Maria had a love-hate relationship because they both had a lot in common. But inevitably one would get more publicity than another. Of course, Robert Smithson's gotten so much attention through the years. One of the reasons is not only that his work is quite wonderful, but the fact that he was a writer himself.

I enjoyed cross-country road trips. And I found the work challenging because it was art that existed on the land rather than mere concepts in a gallery or photographic documentation, or any of the paraphernalia that can be used to indicate that. The art was on the land.

Had opened a gallery I already had strong connections with New York, because I was taking work on consignment from New York dealers. So I already knew a great many of the dealers and the artists here. It wasn't cold for me.

I think that Walter De Maria's Lightning Field, Michael Heizer's City, and Charles Ross's work in Star Axis New Mexico , all three will last for a millennium.
