I think mother Nature got bored and is basically messing with everyone.
Drop some snow, get cold, then throw the temps back up in the 40's.
I was in Lake Tahoe for the past week, when i got there the slopes were green. then we got about 30"-36" of snow over two days, when I left yesterday in the 45º temps and rain I think there was only about 6" left if that.
BTW sledding down a ski slope (even if it's only the bottom little bit) is awesome.
