There is this one hole on my home course where the tee is kind of elevated on top of a hill, and you can clearly see the entire fairway. Three times recently, when my tee shot has hit the middle of the fairway, I have walked down to the fairway unable to find my ball. My playing partners have been just as confused as me, as we all saw the ball land and roll a bit(not getting plugged). We have discussed the possibilities of birds picking up the ball as we walk down from the tee(long walk around the hill, unable to see the fairway), kids pranking us and so on but it seems too unlikely. Only happened to MY shots, three times, same hole. I must have pissed off the golf gods, or we all need glasses?:-P
