When this thread came up again I decided to read the book again. I have it on my Kindle.

In "The Walking Man" it mentions that "The Man From the Cave" was not really a best seller and soon went out of print. The book said that used copies sold for $50 to $275. I looked and found my copy. Amazon used books show $30 to $150. Maybe my kids can make some money on it some day but they will probably just give all of my books to Goodwill.

I do regret giving away my copy of "Complete Walker 1" especially because the person I gave it to left the hiking community in a hissy fit over some minor perceived slight.
