How is that different from us regular joes playing from deer footprints (or kangaroos or haggis or whatever) Pros are constantly getting benefit from spectators (trampled rough, deflecting balls from greater disaster, free drops from stands, finding lost balls, moving boulders, etc.) so its only fair that they have something negative come from the fans once in a while.
It would be interesting to see a tournament where they prepared the bunkers deliberately to be as uneven as possible, instead of smooth pristine sand. Sort of like the turn of the century Prestwick pictures that were posted here earlier this year. Or at least use the special Oakmont bunker rakes on them. The only way bunkers are a hazard for pros these days is when they get on a downslope or have to stand outside it with a really awkward stance, and even then they usually still have a chance to get up and down if they make a good play.
