Only guessing here, but I would bet they open with the additional snow we get tonight. I would say tomorrow afternoon they'lll open Dane Co. I believe our groomer is out right now as I type. (NW quadrant) With a good cold night following, it should set things up nicely. No guarantees on the opening though. Best call first!! Lots and lots of trespassing issues this year already have all the landowners on edge already, so don't push the issue. Only about 5" on the west side of Dane county right now. The other issue is all of the standing water we had, that froze over. Hopefully there aren't any wet spots for the groomer to sink into. Don't expect much if they do open.
