Several of the courses near me have a driving range that is parallel to one or more holes; none of them have any screens along the sides. Yesterday, I pulled my tee shot into the rough that borders the right side of the range side, and knew it would result in walking around for a few minutes trying to find my ball among the range balls. Then without any warning, the sound of a ball landing about 5 feet from me. So I am curious what people's thoughts are. I knew I was putting myself in danger by searching for my ball in that area, but do you yell fore if you are hitting on the range and you know your ball is heading toward someone playing an adjacent hole. I have been hit before (in the forearm) and it sucked, but I saw it coming as it was from a playing partner who shanked a shot. This one was much more haunting as it would have most likely got me in the head with no chance of avoiding it.
