We have begun our fairway aerifications and will try to complete two core aerifications on each course over the next three months and one additional solid slicing aerification after that. This also includes aerifying high traffic areas in the roughs and tee boxes. After we have cleaned up the cores the holes should be healed over in just a few days. Don't forget that if your ball comes to rest in an aerification hole you can take free relief from the aerification hole no closer to the pin.
