They missed "Skiing in the Lake Tahoe Basin". For most of the past decade, the snow pack has been alternating between basically none to decent. Meaning, one season will be pretty good, and the next will have no storms roll through in November/December, leaving them bare for the high season. California may be going into a long term drought and if climate change really screws up rainfall patterns around here permanently, there will be no snow to ski on. I've heard 2050 tossed around as the approximate "no more skiing" date.
That's within my lifetime.
