We put new sand in the bunkers on holes: 5, 6 and 7. It's been over seven years since these bunkers were renovated and had new sand put in them. Over the years, dust, pollen, grass clippings, tree leaves and other contaminants have made their way into the bunkers. These contaminants completely change the characteristics of the bunkers. They tend to become more compacted and hold onto more water. The new sand will keep the bunkers softer and dryer.
