Even with lights, working in the dark has some risks. It's difficult to thoroughly check the greens prior to mowing, observe the quality of cut, and be aware of potential fluid leaks on the turf. Most importantly, we need to make sure the team is able to work safely with limited visibility.
The reward for the effort comes when the Sun rises and we can see the course looking good and ready for play.
