Tuscarora to Missing Link is long but not overly difficult. Don't avoid it just because of its length.
This past weekend I had the 160 rod portage between Tin Can Mike and Horse as the longest portage and it was by far the easiest of the portages. The shortest portage (Mudro to Sandpit was by far the hardest and it was only 60 rods. I would have rather done the 160-4 times then the 60 rod once or twice.
