Concerning pipeweed (and re-reads)

OK, so I'm re-reading The Lord of the Rings. And just in time for my entry into the book proper -- I read the Prologue last night -- I find this quote in a SF Signal post about re-reading books:

Of course there's the Lord of the Rings, which is very different when you come to it at different times of life. I go back to it every six or eight years, give or take, and part of the experience is spending time with the version of myself that read it last.

True words, those!
