I have just found and purchased a new book I spotted at my local store. Train to Barnjum by Randall Probert. Published in 2012 by Randall Enterprises, Bethel, Maine.
Now the way I read books, I should get to this some time in 2017, but it may be long gone by then so I thought I would spread the word now in case it is any good. The book is written about a Game Warden that worked the Sandy River area enforcing the laws.
