Pass the GPS to the kids and let the kids find this one. You can fill out the log for them while they check out the playground. The log paper is rite in the rain, so a bit of water shouldn't be a problem. It will not be a challenge to the adults, so no complaining of how easy it was for you. Sometimes the kids rule, and this will be one of them :) Have fun kids!! OK , so some of the big kids might like it too, and that's ok too :) It's all about the fun!
