Hemingway actually fished the Fox out of Seney - better fishing. Two Hearted is east of there and not as good, but as you say, the name has a "ring" to it. There are a number of good trout streams up there.
This time of the year the smelt should be running. I remember my dad and his buddies dipping nets and filling up the back of a pick-up with em. Took all night to clean them too. Everyone in the neighborhood had gallons of fresh smelt to eat and freeze that next day. Good times.

Smelt! I forgot about them. Fry 'em up and that is some good finger food.
