I myself had lived in the San Fernando Valley many years ago, when it was a much wilder place, and we used to go walking in the wild areas. So that early experience had a lot of similarities for me to the places that Double Negative was being done.

What's happening in the larger world always influences art. When I first started the gallery in 1959, one of the first things I learned was that most people assume artists know one thing and one thing only - that they were idiot savants. I found very quickly that most artists were very informed and very aware of what was happening in the world around them. So all of those things go together, especially for earthworks. And at that time there was such an intense interest in American art. So there was a great deal of attention paid to where it was going.

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.

Quite honestly, even as a woman dealer, I really wasn't interested in masculinity or femininity as such. What was important to me was the value of the work itself. If a woman had come along, somebody like Lee Bontecou or Louise Nevelson, and said, "I'm working on the land," I would have gone to see it.

I think the four land artists I showed all worked within a few years of each other. And they were standard bearers, I suppose, for land art. They each did very separate things. Apparently, later in California, a lot of artists started working in that medium and there was something of a rush of earthworks. But I wasn't involved with that.

Making the effort is quite a pleasure in itself.
