Well in a state with 10,000+ lakes, there's always plenty of boats for sale... Does your fiancee fish? The only reason I ask, is because if she does, you'll be getting a nicer boat
I'm pretty sure that the Ottertail area hasn't been hit as hard as the North, and Northeast parts of the state have this Winter. I'm in area 181, we got 17 inches of snow in the last big storm alone. I can't remember for sure what I heard on the news, but we also either tied, or broke the record for the # of days that we didn't get above zero.
One of the things I'm not sure about in the Ottertail area is the land ownership situation... That said, considering that only 11% of the state is privately owned chances are going to be pretty good that you be able to find some pretty good hunting areas within a reasonable distance. Heck, if you buy the right 40 acres you may never have to leave home too hunt!
