You obviously found one of the rare spots that hasn't been detected before. That's all clad I plresume? Very Nice finds. About the back......I have a really bad back and when it pains me the only way I can get relief is to lay flat on a hard surface. If in a dry grassy area I sometimes lay down on the ground for a few minutes. Someone always comes by and asks if I am OK. I guess it does look funny ? Monty
