Excellent article, JD.  I am certain that we can expect a return salvo from Terry Crawforth who had a 42 year employment history with the Nevada Department of Wildlife and represents the other side of the Thacker Pass mine question, however I believe that Professor Miller has pinned the bell on the cat with his thorough and excellent two part article, this latest one being the second part.  Thanks, JD for posting the link.  Okiedo
