I was there on Labor Day, it was mostly ride-able, but there is some blow down (of course). At that time, I would give it a 90%+ rating for how clear the trails are. That said, I only rode about an hour and a half so I didn't get a chance to see everything. I would say go for it - has likely only gotten better.
Watch out for the widow makers though - more in Bluff than in BR or Arcadia I think on a per mile basis!
