My youngest son took the Geocaching Merit Badge at Boy Scout camp last week. He realized that there was a geocache site just across the street from my older son's taekwondo class. So, we braved the heat this evening to go look for it. We looked for more than 15 minutes. The little film canister was supposed to have a marble in it. The hint said it was between the memorial and the wall. It was last found 4 days ago. But, we couldn't find it (Did Not Find or DNF). Course, we probably couldn't see it for all the sweat running into our eyes. Lesson learned, don't go geocaching when it's 100 degrees F!
