I too have well water and never think about it. It just tastes so fresh and so good. My poor daughter has to use bottled water for everything. I've really been giving this thread a lot of thought and still have no conclusive answers. I remember my grandmother's softened water feeling slimy to me. I'm not saying it was, it just was so different from the well water I've grown so accustomed to.
Oooh, well water! I used to drink well water when I was a child living in VA. I can almost taste it now..love it!
