Query: Gold in them there hills!

Rubie's book is great.I got a copy because I thought it'd be fun to write something out of my usual genre. (Search on author "Stephen L. Nelson" if you want to see what I've written.) And I was really well-rewarded for my reading investment...As an author, there are some things I know about and so get to "double-check" on Rubie's notions and conclusion. In the handful of places where I, as an oft-published author of nonfiction, can test his knowledge, he's absolutely right. Which then leads me to conclude, "Hey, Rubie's probably right about all this other stuff, too."The one other thing I will say about this book--and this isn't a criticism of the book but more advice for readers--is this: some of the stuff that Rubie talks about is a little subtle. If one isn't careful in one's reading, one might miss some pretty important stuff. I think you'd want to read this title more than once...
