On day two I had taken some time during lunch break to hide my cache, complete with enough prizes for all. A friend, the same one that lent me her personal GPS earlier in the year for our unsuccessful trip, miraculously was able to come up with a whole SET of GPS units, six identical ones, and after reading the manual at least 5 times over, I took a few readings from where I had hidden my Cub Cache. Luckily they were all very close, so first hurdle seemed to be crossed. The night before the big day I took some time to program all the units with the secret cache's co-ordinates and make sure they all seemed to be working proplerly. Then it was off for a poor nights sleep of wondering what I was thinking to plan such an activity. Boys wandering lost through the woods for days did cross my poor, exhausted brain on more than one occasion.
The session on this third day began with an explanation of the Earth's magnetic poles and all the kids got to use a compass. They learned how to align it to north, then find directions and headings. Then the true fun began. I handed each of the adult chaperones a pre-programmed GPS unit and paired the boys off. Each adult took two (or sometimes three) boys out at a time to find the hidden cache. The remaining boys got to make their own compasses using a needle and magnet (a VERY cool project to show the Earth's magnatism) and also draw maps of their neighborhoods noting several locations near their homes. To my relief, the first groups came back beaming with their prizes - SILLY BANDS! The rest of the day went off without a hitch, and I'm happy to say that all the boys found the cache and no one was left wandering around the park that night.
