I live within a 1/2 mile of it here in Mass, and a son in law grew up about the same distance from the road, but a few hundred miles further west. At one time or another, I’ve driven most of it in Mass and NY. I don’t remember any “memorable” restaurants, BUT I know the building, that was once a restaurant, where my grandparents met.

Driving the length of 20 has always been a bucket list item for me, but I doubt that it will ever happen.
