Recently I started a series of caches for my geocaching, and they're in the "color my world" theme, meaning the caches are stocked with items of a certain color. So far I've hidden red and green. (Robert helped with the placement on the green one.) Yellow and pink are each ready to go, just have to find a place for them. Blue is not far behind. Go to the geocaching link, and look up GC19HK2. The most recent person to find it posted a picture of the container (along with his kids).
So now I've add the thrill of the hide to the thrill of the hunt!
