You can read a little bit about it here ... news14charlotte.com ... (I don't think that's one of the sites you have to register to read). There are some links down at the bottom with a little more info.
Thank you for the information and link.
In the next few days, I need to write you a freep-mail with a zillion questions. NC is growing on me. You and your hubby may be able to provide some information that I need.
