I got to Old Sturbridge around 9:00, about 30 minutes before they opened. I got finished touring around noon, so I started to head for Sargus Iron works, north of Boston. It was the earliest Iron works, reconstructed on the site. This iron came from the river bed.
This site was originally a part of the city of Lynn, MA but not a separate town in of itself. Thirty five years ago I live in Lynn, along the coast. I never learned of this place. Of course, that was before the days of the internet. I only learned of it while looking online at a listing of patches of national parks.
It is a national park site so I did get the patch, as souvenir. I also got a mug for the mug case, as an extra. Here are the pictures, note I did edit them
