"if you are in the Old Forge area and are interested in a day trip, Mountain Man outfitter/store can shuttle you up to the Rondaxe road for a day trip down North Branch Moose River - flatwater with one portage at the RR bridge (1/4 mile or so).  that is a nice stretch of river, with no camps and no motor boats at all - end the trip back at Mtn Man's store in Thendara."

Well, since Mad Mat's advice is always good, I took it and that is just what I did a few days ago (7/10/15) - Mountainman's rental fleet was about 50 kayaks, 4 or 5 tandems, and one lonely solo.  An Old Town  "Next" solo - kind of a hybrid, sit on the floor - or rather on a lawn chair like seat I didn't like, but I'd brought a seat cushion to raise up a bit higher, and it paddled well enough. portaging it would have been painful with that seat arrangement, but I used the Type IV cushion as padding, and it carried ok, if a bit heavy at 60 lbs or so.

But for $46 plus tax ($48.50 or so) that included the shuttle to Rondaxe Rd., it was a nice deal.  Took me 3 hours, including the 1/4 mile portage - apparently that was a "record", as all 3 of the guys from the rental shop were amazed I was back so early - they say allow 5 to 6 hours. Something between 10 and 15 miles - would have to look it up.

I hadn't done that stretch of the Moose river in maybe 15 years, and it was nice to get back on it - good current helped (from a lot of rain several weeks in a row earlier on).

So if you are up in that neck of the woods, it is definitely worth doing.  Mtn man will shuttle your own canoes if you have them.   I had a 15' Grumman I could have used, but the $46 rate was a lot easier than cobbling together a boat rack to carry the Grumman, and the Next did paddle easier than the tandem would have, and portaged a bit lighter as well.
