The open at Oakmont is underway with some very interesting weather. The superintendent there believes in some of the same maintenance practices that we implement here.
I am linking some the video from the USGA website with a story on the fact that they vented and also topdressed all the greens at Oakmont 6 days before the open

I will be vent or needletining the greens starting Monday this week and also will apply a very light topdressing
Hope that you have a great weekend
