I have to admit I really enjoyed the book upon receiving it. But then when I actually looked at the map detail on a couple trails I was preparing for, I noticed the colored trail information was completely missing. In other words, the trail was omitted from the map page on 3 of the 50 trails inside the book. Naturally, it was on the 3 trails I was seriously reviewing for trips. Page 87, 95 and 105 have no trail lines printed. I am sure this is a printing error. I sent an email request to the MFR for a replacement copy to be sent to me at once. Once I receive feedback from them, I will add the resolution information to my review.
