These reports are not up to date. Just like SB, mad river glen saw 1 foot throughout last week and another foot on Saturday night. Then another 2" last night. Conditions are excellent. They range from powder to thin cover due to the light fluffy nature of the snow.
I would say they'll be 90% or better by Christmas. The warm up/rain forecasted for this weekend will slow it down a bit, but the following week is supposed to be cold so I imagine they'll blow as much snow as they can for the holidays.
