"I leave it up to the viewers. If it’s in a museum, if it’s in a gallery, usually I am going to point out something about a river right below your feet or right outside your window. I’m not going to scream it out. If you get a little curious, you can find a little bit more. At times my works are maybe to a fault subtle. For public works, maybe you won’t even notice I was here. I’m not trying to defeat or conquer nature."
