The Knack! guide format of using photos to enhance the (very brief) written descriptions reminds me of the Teach Yourself Visually series. Tilton's tips and suggestions to become a better BPH (backpacker/hiker) were excellently complimented by Gorman's photography.
Overwhelmingly, the information was not new to me - but, I did welcome the refresher and feel a bit of motivation to get on the trails again (perhaps not backpacking, but at least back to hiking more regularly). Regardless, I would say that it's an excellent resource for those just starting out as well as intermediate BPH that want a handy resource to consult for basic information on just about every topic relevant to trailcraft.
Started this book 2 weeks earlier than date posted. Lots of pics and solid advice for backpacking. Not quite what I was looking for. I am looking for comprehensive guidebook for the AT. All in All good, quick read.
