I've got a season pass to Crystal but don't get up there as much any more since I also have a 9mo old daughter at home. I may be up there for a day next weekend (Jan 26/27 or thereabouts) maybe over Prez day weekend in Feb and probably a last hurrah in late March.
This thread on the forum is pretty active so don't be a stranger! Mostly metro-Detroiters but there's a few from around the state and we do try to coordinate who's going where & when so we can meet up.
The last few days have looked beautiful from my perch on the couch. Seems like great days to get out there.
