There's not much snow in Tahoe, so my 'Fair-' is relative to overall conditions. Not worth $101 unless you're rich or desperate. But if you have a Northstar pass, it's still kind of fun right now.
There were very nice man made snow conditions over the weekend with a few hard bits and bare spots but nothing too bad. I had a fun time screwing around on skis one day and a snowboard the next, as did my wife & kids. The place was empty and the sun was shining.
Nstar says 27 runs open. All I can say is that if you explore a bit there's just enough terrain open to keep you amused, but no more.
From what I heard, Squaw and Alpine are pretty much a dead loss right now, but I didn't go there myself. Sounds like Northstar or Heavenly have the best snowmaking & are the only games in town right now...
