I thought about this thread when I was playing Pasatiempo this past weekend and saw something that I had not seen in my 10 years playing the course.
The 11th hole at Pasatiempo is a very tough, uphill par 4 requiring a carry (usually) on your second shot over an arroyo. On opening day at the club in 1929, Bobby Jones hit it over the arroyo on his tee shot and made par, but over the years trees have grown up next to and in the arroyo, making such a shot basically impossible. Nor is such a shot desirable from a design perspective, since the next hole's fairway is on the other side of the arroyo.
On Sunday, from the back tee, I saw a lefty line up his tee shot way left, and he drove the ball directly over the 12th green flagstick with a big draw, around a tree that sits behind the 12th green, and around the arroyo to the left, basically avoiding the arroyo by going around it. It was a terrific shot, requiring a long, big draw from a lefty, but it was clear this guy was a player.
Normally, the trees in the arroyo and the tree behind the 12th green would discourage anyone from trying this shot, but it's funny how a lefty with a big draw could pull this shot off when I've never seen (nor thought of) anyone being able to do it. It's not something that the club would like to see repeated very often, given the danger it poses to players on 12. The tree behind 12 is clearly going to have to get bigger.
