I'm hesitant to reach out on Christmas Day. It's been a tough month and I'm sure Laz could use a break.
The conditions page (updated 12/22 or 23?) implies the double will spin but I'm wondering. Have they blown on the double side? If so I haven't seen it.
If there is no manmade base, so I don't know how they would groom it. Logical to assume there is a crust with some dust. Maybe you could groom Ridge.
