The one thing I miss is hitchhiking. Now there's no more of that. When's the last time you saw a hitchhiker? It's not that I consider it a great sport, but it was my way of seeing the country. The open road, especially in the western United States, is still very pristine, but everything else around it has changed.

Basically everything I've done in art, I was in possession of when I was 20 years old. I use a waste retrieval method of working. I'll go back and use something that disgusted me 15 years ago but that I had enough sense to think about. Some artists change dramatically. I see my work more like history being written.

I'm interested in glorifying something that we in the world would say doesn't deserve being glorified. Something that's forgotten, focused on as though it were some sort of sacred object.

I think the most interesting stuff comes from people who've just got nothing to lose. You know, let's kamikaze this thing - just throw themselves in it, devil may care.

Unfortunately, there was no Jackson Pollock of the camera.

I knew I wanted to be some kind of artist from about 12. I met a neighbour who drew cartoons, and I had an idea I wanted to be a cartoonist - or something that involved Indian ink, at any rate.

There was no hope for any kind of big opportunity. I'm not saying it was hopeless. The big pay-off was to work as an artist and gain some shred of respect from your friends, who were also artists. But there was never any notion that you could make a living out of art. On the rare occasions you had a gallery show, and sold a little work, well, that was just gravy.
