I take that back...
Based off what I have been given as info, they will likely not be spinning the lifts this weekend. They are hammering the upper mountain hard with snowguns, but they are holding off on snowmaking near the base. They will start snowmaking at the base once this little hiccup passes on Thursday, Friday and Saturday as temps drop hard Sunday.
Looking at everything, there are a few reasons why Killington has no push to open up this weekend.
1 - The opening date is already in the books as the 2nd, and bragging rights are done.
2 - No other ski area in the Northeast will be open this weekend, so no real push to make snow that will melt-off
Shitty, but the random weathher this fall is crappy for early season openings.
