No pics because its been a few years but it’s in the Minuteman National Park, went on a tour of the area a few years ago with a few friends for a trip we did together to sightsee the East Coast US.
Been lurking here for a bit, made an account just to post that I’ve actually been to the irl location and it’s just a bridge with a patch of ponds behind it. It’s a part of Concord irl. But the “cul de sac of Sanctuary” is just a pond irl. Cheers.
