Tyngsboro, MA

PO Tyngsboro MA

I wondered why a bridge would rate equally with the post office, but I learned that Tyngsboro, Massachusetts, is on the border with New Hampshire, and the bridge is a landmark. This one was replaced in the 1930s with a steel arch bridge, a landmark today.


Warm Springs, MT

PO Insane

Warm Springs is today the site of the Montana State Hospital, the state’s only psychiatric hospital, founded by the Territorial Government of Montana in 1877, and there is still a post office (zip code 59756) on the hospital campus.
