Do you remember as a child turning over a garden rock, to find a damp collection of small creatures, Rolly pollies, spiders, worms, centipedes and so on? Most of us were eager to investigate the creatures we found beneath the stone. Though some of us were scared of spiders and all forms of creepy crawlies, we were still curious enough to lift the stone. I was one of those children, scared of what I may find beneath the rock, but still eager to look.
