You put your bentgrass in my bluegrass

We receive some complaints about the length of the rough at times, especially around the greens. Mostly, these complaints involve what I refer to as contamination. The bentgrass from the fairways, greens, and tees, has escaped in the rough and surrounding areas.
Certain times of the year, it can be seen vividly.
Here are several photos of the contamination, as the heavy dew allows the bentgrass to appear as the light green areas.
Our committee is working hard on several possibilities for solving this often frustrating circumstance.
Enjoy the day,
