It would be great to get together with you to do some detecting I've never swung one. LOL. I have COPD also, kinda slowed my rehab cause it's tough to walk far. Still smoke and that don't help. If you think about and are kind enough would you be willing to bring some dirt back form a wash or crick that MAY have some color in it. Or maybe dry some out and throw in a usps box. I don't see me getting down that way anytime soon. John
