I skimmed the article, and to tell you the truth, it is one of the better articles I have read on the sport. It sheds a very positiveimage on Geocaching. The artwork is the only bummer, and is probably due to the fact that the artist had nothing to do with the article itself.
I think the only reason people assume caches are buried is because the word “treasure” is used way too often to describe a cache. People hear treasure, and a few words come to mind–Gold, Jewels, Buried… and NONE of these fit a cache. Why do so many people within the community insist on using the word then? Perhaps if we made a concentrated effort NOT to call Geocaching a “High tech treasure hunt” the assumption that they are buried will be less severe. Seriously.
