It was put back to keep node history while reducing it's purpose to an address node.I did not remove the GNIS tags since I was mostly just restoring the history of known post offices that were deleted due to the Historic labeling.
The address is correct so at the very least it would continue it's life as an address node. The building at that address still exists so having the details in the node that it's recognized as a historic building is also useful information.
In this instance the post office has moved but the road is also referred to in resources by it being an old post office road as well.

I reverted this change set and modernized the node information to preserve some history.
The dam is no longer there (unsure what date) but documents seems to refer to the falls as Ledge Falls (hence the name of the dam being Ledge Falls Dam)
The church, while I didn't verify if it's a historic building, still exists at the same spot without an OpenStreetMap POI.

`Coastal Route US 1 // US 1 (Coastal Route)` is displayed on the signage as if it's a destination:ref:to. The `Coastal Route US 1` is just a portion of `US 1` that runs along/near the ocean and seems like it would function as a reference either in of itself or a modifier to the `US 1` destination:ref:to much like `SR ## Business`

I reverted the change I made so it's back in the `destination:to` section until there can be a decision if it should stay or be a separate `ref:to` or a modifier.

Accidentally modified last year, that is.
