Someone mentioned a haha. When I think of a haha I usually think of a road beyond it. I guess it could hide a ditch. Also, most of the ditches I am thinking of would not necessarily hold water (similar to the ditches at Oakmont). They would carry it away or simply act as an asthetically appealing open drain. I was just out at Oakmont last week. We teed off at 8:00 AM and they had 1 1/2 inches of rain the night before. There was no standing water in any of the ditches (at least all the ones we looked at). I think almost all of the time they are dry. As I said in my first post, Forrest and I are going to use quite a few on this current project.
