Query: I don't need a rockhounding book to tell me about sites I can't access

I agree with the previous reviews that this book has too many off-limit sites. I only spent $8 on this book used but I'm truly regretting the purchase. There were 50 sites near enough to visit on my way to Phoenix, the 5 most interesting ones are prohibited (2 with full-time caretakers to keep people away), and only 4 besides those 5 that I would consider visiting, but aren't extremely appealing anyway. It is not worth purchasing the book - rent it from a library if you feel the need to read it.Too much of a history lesson than a rockhounding resource.
