I just drove down Ardmore Avenue this morning, and noticed that there were a number of fairly large pine boughs down on the right side of #2 at Merion. The good news is that the weight of the snow down here seems to have impacted the pines more than the hardwoods, which in my view is a good thing.
As for the impact of snow and ice on greens, I think this winter is closer to last year than the winter of '98 (?) when we had a 3 inch layer of ice directly on the ground, keeping oxygen away from the plant. Rolling Green's greens are covered, but according to Charlie Carr they're getting plenty of air.
