Spong, if you go down to the mill, you first need to stop in at the company's main office and sign a waiver before you can visit the mill (i have directions if you need 'em). Ask for a tour; anyone at the front desk can help. Hopefully, someone is available to take you to the mill (I've had 3 so far). You will be impressed as others have...
BTW, very interesting that you should mention RZ..... I know all about this company and have followed for the past 6 years (love to tell ya my story about it some day!!). Ya know, imo, w 100,000 acres available, one would think CPRK would have other resources besides minerals contained in the ground.
