When do they start grooming the trails?

[TWOSTOKED]

Anyone know if grooming has started at Crystal Springs?
I tried looking on the snopark page for grooming updates for Crystal Springs and this is all it said.

2015-2016 SEASON:
GROOMING UPDATES

12/7/2015-12/13/2015: There is no scheduled grooming at this time; Grooming may occur if there is snow. Check back for updates.

I think there is snow.

I'd guess there is not enough snow just yet.
