What should I ask David Salle?

Yes, the famous painter, I am slated to do a Conversation with him.  Here is the beginning of his Wikipedia page:

David Salle (born September 28, 1952; last name pronounced “Sally”) is a Pictures Generation American painter, printmaker, photographer, and stage designer. Salle was born in Norman, Oklahoma, and lives and works in East Hampton, New York. He earned a BFA and MFA from the California Institute of the Arts, Valencia, California, where he studied with John Baldessari. Salle’s work first came to public attention in New York in the early 1980s.

And he has written the well-known and excellent book How to See.  He directed the Hollywood movie Search and Destroy, starring Christopher Walken.  So what should I ask him?
