Well, One when I was showing my friend what geocaching is (by checking my own at the same time) an old couple came. There I was, with the cache in my hands explaining about gps, logbooks etc when they searched for it, right next to me! I asked them if they were looking for something, and they said that they was looking for the box i had in my hands. We stood there talking for a while . It is always nice to meet others while searching for a cache.
