As you can see from Brian Thomson's post yesterday, it was a rough year for greens in Chicago. Here is a post from Ben McGargill, Supt. of Wynstone Golf Club which is just down the street from Biltmore. Ben's greens were covered during the winter. He sent me this picture of the 17th green where the left side had remained uncovered. Ben made no attempt to remove the ice. His greens are mostly Poa. As you can see, the Poa did well under the cover, in spite of the long ice cover this winter and the uncovered area was damaged.
I'll post some of my own thoughts on winter damage tomorrow.
