I have followed David on YouTube for quite some time. It was only later that I discovered his Instagram feed. David and Beth are magnificent examples of a family building a purposeful self-reliance lifestyle. Naturally the bonus from our perspective is their ham radio and first aid expertise. Both are valued assets in the ham radio and preparedness communities.
David and Josh have provided an impressive resource list for the topics covered in this interview. However, being honest, it goes much further than that. Please take a look.
