There were many encouragements to Ken during his five-year diary called Ken's Greatest Challenge, many heartfelt and inspirational messages from family, friends, coworkers, students, those who knew Ken, and those who knew about Ken.

This guestbook is a collection of these messages that were all read by Ken. He appreciated these so much. I believe that these are what kept him so very positive and fighting for as long as he did.

I thank you all from the depths of my heart as to what it did to encourage this very amazing man.
