Jim,
I'm a big fan of the aesthetic bunkers that really shouldn't come into play strategically on a hole, but seem to stare you in the face on the tee box. For instance, the par 3 third hole at Pasatiempo has a bunker about halfway to the green. It just frames the hole beautifully, even though you're going to be landing the ball 50-75 yards further. (If I can figure it out, I'll post a picture.)
