Some of the courses offered by his organization are pretty hardcore hunter/gatherer stuff (at least according to the course description). But Lundin communicates over and over again the importance of carrying a modern PSK and at any moment using whatever works best.

To be frank, some of the "back to nature" and "the more you know, the less you carry" school of thoughts makes me sick. Nothing wrong with a skilled person making do with a pair of pants and what nature provides, but those that are capable of such stunts have spent years and years learning and training. Before you spend time learning all the finer points of making a bow fire and finding tinder when it's wet everywhere you should have a black belt in using lighters and vaseline cotton balls.

On the other end, you have the "all you need is your altoids tin box PSK and a space blanket". Equally wrong. A PSK must be adjusted to fit the environment. A space blanket in a pocket is sorely inadequate for many environments.

Cody has a very well balanced and well thought out balance between old and new, mixing knowledge about physics with ancient skills - whatever works best for the moment.
