Thanks, I appreciate that! (Which I swore I typed a few days ago, but apparently forgot to hit send.)
I wouldn't need to access Orphan Farm anyway: this would be our last day of riding, ending at the Wassaic Metro North station where we'd catch a train the rest of the way home to NYC.
Neither Komoot nor Google suggested that route through the MA and NY parks - I imagine because of that slope which is apparently >= 10% for nearly three quarters of a mile, max of 18%. That's pretty dang steep, but I think we'd be fine either taking it at a crawl or, if necessary, walking the bike down the steepest of it.
That leave give us something like this: (https) goo.gl/maps/CxYP3iLjoBuxX8M96 - look about right?
(Aha, bikeforums told me I don't have enough cred to post links... probably didn't notice that while trying to reply the first time.
