You'll be fine. I skied opening day at Mary Jane last Tuesday. Things were a little sparse, though good snow on many runs. They've gotten significant snow since then, and more is expected. There will still be some of the steepest stuff unopened, but you'll have lots to ski. Enjoy.
It's looking good. More snow is on the way. Outhouse needs to fill in a little more. People were sawing down small 1/4" saplings with their skis on Saturday.
My buddy that works there saw this as well. Said a patroler was sking down a hill with pruning shears topping all the trees that were still poking through. Solid snow recently and he says the snow is quite good since then. I'll be there 20th-24th and then again from 28th-1st.
