I play public muni courses and often people either don't know or don't care about properly fixing footprints in bunkers. It finally happened last time out ... my ball wound up in a 4 inch deep footprint. Someone didn't even make an attempt to rake their footprints. Simply no humanly way possible to get the ball reliably out from that kind of lie. Now, I know we have to play it as it lies, but comon, why should I be penalized for someone else's carelessness ? I moved the ball a few inches over on the flat sand ... no way I was gonna let somebody else's carelessness potentially ruin my round (that lie was so bad I could realistically see it costing me several strokes that I shouldn't have had to lose). Those footprints were so deep it took me a couple minutes to rake it properly so the next guy wouldn't have to deal with it.
If this has ever happened to you, do you just chock it up laddy as the rub of the green or better your lie ?
