While we will never settle the debate globally, employees at Cinnabar are instructed to place bunker rakes in the flats of the bunkers. Where the bunker rake goes from there is up to the golfer. This does provide a couple of advantages for us. One, the golfer is more likely to see it and use it (not always though), and two, it allows us to mow the bunker surround without having to get off the machine and move rakes.
If your ball does land in the bunker and is rested against a rake, follow USGA rules if your ball moves from its original spot.
Thanks to a previous commenter, Dave, for providing a great blog subject! Didn't necessarily provide the answer you were looking for, but we've certianly kept the Great Debate alive.
