There are a lot of things I agree with him on - wet feet, clothing, etc.

Some of his advice is likely to lead regular ol' backpackers astry tho. He has NOT been correct in his assumptions about food storage in the Sierra - they have not "outlawed" bear bag hanging, and he is dead wrong that canisters would not be necessary if everyone could hang food properly - they are absolutely necessary in Yosemite where the bears have proven, time and time again, to be able to defeat properly hung food.
