Huge staffing issues in lift maintenance and general lift issues are pushing slidebrook to the end of the priority queue unfortunately. There was a blog post on their website about it somewhat recently. Re: Castlerock, they usually keep it hike-to for a bit to preserve the conditions early season since those are super boney and narrow trails that get scraped down pretty quick. I agree though, there is definitely more than enough snow now to open it for MLK so if that doesn't happen, you'd have to think there is another maintenance issue we don't know about. Personally I hope they keep it hike-to only. It's a quick fun trek and the snow stays soooo nice even on busy weekends.
