When we me TandemStoker at that location a couple of weeks ago, we discussed the history of The Somerset Railway, and I mentioned a book that I had read on the subject: "
The Old Somerset Railroad", by Walter M. MacDougall. I looked for it at the time and couldn't find it, but your mention of history prompted me to look until I found it! LOL!
It's quite a story of a railroad through the woods - Oakland to Mt. Kineo on Moosehead Lake. Hopefully I'll be able to get a couple more caches along the route before Laughing Terry has all the good locations locked in! LOL!
