Greens that make me happy

Today is the second day of "president's cup," here at Briar Ridge. We hope the greens are rolling smooth and true. More important than speed, is the trueness and uniformity of the surface. The photo demonstrates a tool that I absolutely love....the prism.
The prism allows the ants view to the superintendent. The quality of cut and the true mowing height can be seen through looking down through the prism, which changes the vantage point to horizontal over the Turfgrass canopy.
The putting surface appears uniform in height, with a nice clean cut. I'm gonna hug my mechanic now.
Bravo Leon, bravo,
Turf
