The MTA experimented with such a bus, on weekends only, but there has been no bus service to Wassaic in recent years.

He wrote about this in the Berkshire Edge (click to read the article) in 2017.  Elitzer’s financial model, he said, demonstrated a possible break-even scenario that wouldn’t require a public subsidy, but to date there have been no further developments.
