Thank you. I was just doing a bit more surfing this afternoon and I am working on this...Duncan used the alias geocaching.com on some of his posts. Did a google and find that
orienteering is a big part of geocaching. I don't know how to post a link, but go to... http://jeep.geocaching.com/
Wasn't he in a Jeep? Didn't they find a Jeep tag in one of the state parks? Could this Geocaching stuff be related to his travels?
Time for my tin foil hat?
