Suprised they are not blowing/opening more trails.

I don't think Whitetail has said anything officially, but there have been reports on some Whitetail-focused Facebook groups that the snowmaking pond has been quite low due to the significant drought this past year.  (The pond is north of the resort on Blairs Valley Road, headed towards the golf course, so it's pretty easy to see it's not at the levels one would hope.)  That would require the resort to be thrifty in how it applies its snowmaking power.  On the plus side, there might be some significant natural snow coming this weekend (maybe even 1-2 feet), so that should help out!
