This cache is hidden at Francis William Bird Park, in Walpole, MA. The park has many walking paths and lots of beautiful scenery. I also recommend checking out the other caches and Adventure Lab here if you haven't already! BYOP.
Note: you don't have to cross over the brook to reach the cache. It's reachable on land by a small geo-path nearby!
Congrats to robar on the FTF!
