Wow, the way you describe it, it does sound quite a bit more dangerous than I had previously been thinking. Maybe it was the septic thing that got me. I really don't want that harmed. We have too much clay and I had to make a cap and fill. A total pain in the ass. Well thanks a bunch for the heads up. Who knows, you may have even just saved a life or two. That's great to hear about your child. At age 4 he still has chosen not to tell us what his powers are.
