Don't bother.
Well, you just can't judge a book by its cover anymore. Here was a black and white photo of what looked to be an acorn the size of a large boulder, and instead, well, it wasn't. Few pages, big print, uninformative, and over price. Otherwise, it was fine. Hah.Not something I am going to keep when I move again. Stick with the Ansel Adams series. I wish I had.
