In the popular series books , " GPS for Dummies" , on page 118 , the
starting chapter on 'geocaching', there is an insert referencing
"Letterboxing " and it's site: Letterboxing.org . It talks about
earlier geocaches being letterboxers and that there were letterboxer's
before geocacher's........So geocaches should have some respect for
letterboxers since their hobby is partially derived from them.

read it yourselves and see what you think

clicking on the "globe" and also the "Central American/Canadian" icons
on the LBNA USA Map Page.
