After several grueling days of tracking the beast down I finally caught up to it.  It was headed towards Rockford, Ill. as I suspected it would as I'm thinking that it wanted to take revenge on Marten. 
Pics to follow.....I'm hoping

I finally caught up to the beast (when northerns get that big they actually loose their spots) after several days of camping out on the lake in sub zero weather.  I was a bit warmer than when I tripped with Jimbo and Magic in Q and my xped pad would not hold air.  Anyway, I knew the beast was out to seek revenge on Marten so I drew a line between the beasts last known location and Rockford.  That's where I laid my ambush.  I was alerted to its presence by a flash of something pink hanging out of its mouth and trailing fishing line sightly larger than the anchor rope on my power boat.  After I speared it I had to tie the rope from the spear off to the hitch on the Jeep to pull the beast out of the water.  I can now understand how the beast pulled Marten through those lakes and across the portages before it broke off.  (By the size of the line/rope Marten was using he must have cut it to prevent being dragged back into the states.  I didn't know that they made 64,000 lb. test Fireline).  It was a great battle but I finally prevailed.  Wondering if Marten can do a positive ID on the beast??
Tomorrow's POD will demonstrate that I am master of our domicile......if, and only if, the troll is not home
