Or is it an 18-hole miniature golf course masquerading as a sculpture exhibit? For a $6 admission fee, you can play the course, ogle the art and decide for yourself. Museum officials say that, just as miniature golf made an elite game available to the masses, they're trying to bring modern art to a broader audience. And they boast that every work of art is "playable." The curator's only plea: "Please play gently!"
