TB  we started at Rice Lake and made it to Little Pine in about 3 1/2 hours.  If you wanted a longer trip I would put in farther up river from Rice Lake. That area looked pretty remote no cabins, boats ect.  Like I said the water was a little low in the first week of August.  Would be a lot more fun earlier in the year with more water. I have a cabin on lake marion so the otter tail is in my backyard, I will have to try out some of the other sections of the river in 05.
