I always move straight to the 'later events concerning the fellowship' section when I finish with Sam's immortal words.
It finishes the book beautifully for me. And it still brings a tear to my eye in places, especially when the 'beds' of merry and pippin and moved either side of Aragorn's tomb in Minas Tirith.
And I like the idea that it's a 'tradition' that Sam followed Frodo 60 years later. Did he actually get to the undying lands? did he meet Frodo? was frodo dead already? Was Sam actually allowed to follow him, or did he spend the rest of his years looking out over the gulf of Lune and die peacefully at the Havens?
PS the tale of the years is also helping me put together a script for the 3 season mini series of LOTR I'm writing....

I'm not doing it the way tolkien wanted - writing it happening as the tale of the years represents.
