The NYT hardly "found" Esalen. The thing is around since the early 60s. And has been home to people like Timothy Leary, Buckminster Fuller, B.F.Skinner, Virginia Satir, Allen Ginsberg, Joan Baez...
It's a rather well-known home of counter culture. Silly Valley simply hopes something rubs off on them. Because the realization is starting to set in that you, after all, really cannot take your toys with you.
But really, "finding" is a pretty strong word for writing about one of the major touch stones of 60s culture.
