Zero-Zero

I just noticed that a hiker I briefly met in April 2008 will be speaking at a showing of a National Geographics film on the AT.  I had had a conversation with Zero-Zero at a shelter we were camping, and did not know he was blind until someone told me the following day.  The article below says that Zero-Zero also hiked the Pacific Crest Trail.
