Steve, I'm just getting around to replying to your "walk" message, which I
had saved.  I really enjoyed your description of the walk and the excerpts
from Twitchell's letter.  I definitely want to take this walk someday and
see if it is as stimulating as your description.  In any event, keep up the
good work.  It was a pleasure to meet you in Elmira.  see ya, martin
