Open on temporary greens only

Looks like old man winter finally found his way to Northwest Indiana.
We have put the greens to bed for the season. The photos show the application of sand, a final topdressing for 2012. The grass will now be dormant until spring when we will count growing degree days to predict the return of growth to the plants.
The turf is closed to winter play as frozen root zones could result in damage to the surfaces. Today, we will be shooting a video to examine the reasons why we close the regular greens. Look for this to come out later this week.
The temporaries are located on the original back nine, 1 and 9 white, 1 blue, 4-9 blue.
