Thanks so much for sharing that.
As the "grandfather" of internal frame backpacks (so to speak), I certainly believe I owe him a debt of gratitude.
As sad as it seems, I'm glad to know he is embracing his last adventure in a Good Way.
To this day, I still whip out my 105L Lowe pack when I am required to carry pretty much every piece of gear I have.
Or for the backpacking trips w/ the wife & 3 kiddies.
