LOL there is a bridge simular to the one in your photo where i live. you cross that bridge, it takes you to the remains of an old fish hatchery the state had, to stock fish in the lakes, rivers, and streams in Maine. next time i go out, i will get a photo of the bridge. but crossing that bridge, and finding the remains of the hatchery, is a bit dangerous. do to a lot of bear activity there. even though the hatchery is torn down, bears feed in that river to fatten up for the winter.
but will try my best to get photos of the old fish hatchery remains. can't promise that, but i can promise a photo of the bridge.
