"Do not depend upon a map and compass unless you know how to use them" - a good statement, and I don't think anyone would quarrel with the wisdom of such an utterance. Doesn't it apply across to board to most of the skills and gear (toys) that we drag into the wilderness? - Don't depend upon a rope and carabiners, don't depend upon a stove, or a tent, sleeping bag, etc. ad infinitum...

Gear is easy, skills are hard, to acquire. I long ago ago learned to look askance at the dude with all new bright shiny gear - nearly always the sign of an affluent, unskilled newby. The real ones have a spectrum of vital necessities (toys) that range from well used to shiny new.

I think a lot of the regular posters here have stated this principle numerous times in a variety of settings. They are absolutely right.
