Thanks for the picture! I found some information on oiled sand greens online. Some are oiled with used motor oil, some with fuel oil, others with soy oil. They claim that once the oil has soaked and 'dried" in the sun, the sand will not stick to your shoes and the oil stays in the sand. One article I read claimed that oiled sand greens were more consistent for ball speed and roll than grass greens. I still haven't decided if we will play AGC, but if we do, I will definitely post a report.
