Nah, I see it as more of a depression around an underground drain line. I say that because the course I played throughout high school had one of these on the sixth fairway, and the super was working on it this year when we rated the course.
It was always just the general area/through the green. Sometimes it was a little longer, but it was even a little wider than this one seems to be.
The water goes under the ground, through a drain line. I believe this one is actually that, too.
Thanks and I know. Majority of these are not 'worded' thoughts but is about keeping all joints soft through the swing and the soft focus is about keeping centered pivot as much as possible. While swing is not great, and width is still a work in progress, these allow me to play manageable golf.
Standard 45.75" on the Mav Max driver. I have thought about taking a 1/2-3/4" off of it but don't like to mess it up. Once off the shaft can never be put back on to satisfy me, psychologically. So, for about 20% of the time, I just choke down on the club a bit to accomplish the same thing.
