What is the most socially conservative county or town in the Northeast?

There some towns that are heavily orthodox Jewish.

Kiryas Joel or Lakewood, NJ would be my answer for this. There's also a couple of small towns on the Jersey Shore founded by very devout Protestant communities that to this day are still dry towns, though I think they have secularized a decent amount in the past few decades
