Lines in fairways

We have some paint markings in the fairways and approaches. The fairway lines are marking new mowing patterns. We do this to try to change up or decrease the amount of grain in the fairways. I like to mark the lines to make sure that the guys keep straight mowing lines.

The lines in the approaches are marking where we sprayed pre-emerg up to. We use a different product around greens than we use on fairways, and we mark where the sprayer stopped to make sure there are no skips in poa control.
