That last line there would make a fine companion to Rick's line about canoes.
Maybe we should compile a catalog of Items That Have No Place on the Golf Course.
I'll add one: Anything that has ever been marketed as an aid to business efficiency has no place on the golf course.
Dan,
Personally, I'm all for uncertainty, unfairness, ridges, ripples, heel-marks, profanity-spewing caddies, boiling oil, snakes, WMD's, dethroned despots, dominant leather-clad women of ill repute, and just about anything else you can imagine in your nightmares as fair game within a bunker. It's a hazard, not something akin to what where we spent time in kindegarten.
If you want to add a medieval torture device with that heavy rake to dig furrows in the bunker that's cool, too, but it should be utilized to beat the player over the noggin while he's trying to extricate himself.
Perhaps you think these are draconian measures, but think about what our golfing ancestors were going through on a daily basis in their non-golfing lives. When they weren't being beheaded like Mary Queen of Scots, they were being drawn and quartered in the public square like William the Conqueror, or just lining up against the competing country/religion at 100 paces and charging with spears at each other.
In contrast, a rugged bunker must have looked like a fun little penance to these folks.
In our cushy lives, we thankfully don't face much in the way of danger and real peril on a regular basis. So, it amuses me somewhat when I hear people complain that they had to play a golf shot from an unmanicured bunker.
There's no excuse for lack of manners, and I think you can leave a bunker better than you found it if you try. I just think we've gone waaaaayyyy to the other extreme of soft expectations and I can't support it.
BTW, other things that should never be found on a golf course include range-finders (I swear I'll walk in if anybody in my foursome ever pulls one out), iron-covers, carts with a pad for a scorecard and pencil, and ball retrievers.
