David believes that knowledge, skills, and attitude – as well as proper mindset, trump having the newest or fanciest gear.  David is a DIY prepper, and likes to think of himself as a prepper macgyver that is able to take academic knowledge to formulate on the spot solutions to a wide variety of problems.

He doesn’t teach from a high academic pedestal, spouting what he once heard somewhere, or spend the majority of class time with war stories designed to stroke ego.  He spends class time teaching what he knows works and passing on both what is needed to know to get the job done.
