Thanks for your response, John! I believe the rights are for land somewhere near Hazen; perhaps then I should start somewhere around the Recorder's Office for whatever county that falls in? I know the info you cited as being necessary to hone in on specific facts exists somewhere in my messy home office, so I likely won't be able to take the next step without first finding that documentation. Sigh. I doubt we're talking millions of dollars, but whatever the worth, I'd sure hate for it to go to bureaucrats! As to gaining info "relatively inexpensively", to what type of firm would I direct my inquiries once I lay hands on the specifics... Thanks again! So kind of you to post a reply...
