Near Dead Men's Respite (the tomb you go to retrieve King Olaf's verse).
EDIT: M'aiq welcomes you to the forums. M'aiq wishes he had a stick made out of fishies to give to you. Sadly, he does not.
It is on the road between Dragon Bridge and Rorikstead. If you stay on the road you can't miss it; it is the first bridge north of Rorikstead.
*facepalm*
I left you a linked pic to the exact location in your other thread... this morning...
I love Robber's Gorge. It always makes for a fun fight, ESPECIALLY with Organized Bandits of Skyrim installed.
