"When  four hobbits and a ranger find their way over the Last Bridge and into  the Trollshaws they come upon a strange but familiar sight: three stone  trolls." Though these three louts are the icons of the Trollshaws, there  is a lot more to it than just Bert, Tom, and William. Merric of A  Casual Stroll to Mordor joins me as we sift through the autumn leaves  and ford-water to find out more of this zone.
