In the years when I was trying to get my work shown and accepted and so forth, I went to work for the Pennsylvania Railroad and that was my formal art school. You can learn a hell of a lot about sculpture, working in a railroad. The thing about getting a job outside of art is the fact that you can finds out whole areas of materials. I don't mean new ones. I mean old ones like scrap iron. A railroad is essentially a big collection of scrap iron, and that's why it's great. You get out and beyond the art confine.
