We had one at the course I belonged to in Illinois, the tree was just behind the bunker, but it grew down into the bunker, so you had to grip down to the metal and it a low shot that stopped.
I always liked that because I spent about 3 hours one weekend late in the day, and learned the shot, while for 30 years, I watched everyone moan and grown about that tree, "How unfair it was, etc" and I kind of just chuckled.
