Somewhere in the deep wrinkles of my brain lives a prepper. It shows up when I see a sale on shelf stable snacks and I think, "If the shit hits the fan, it would be nice to have a few of those."
Lately, I have been looking at Meshtastic. It is really cool tech and objectively useful for disasters. Then I remember the catch. I have to convince the people around me to actually carry one for it to matter. Building the mesh is easy. Building the social buy in is the real work.
