In my group, I'm the one who barked about hygiene and sanitation first and loudest.Lack of sanitation will cause the return of many waterborne diseases that although once common are hardly seen today in this country. These have killed more people than all the wars combined.
We've taken this onboard.
In a prepping world where people are freaking out about forever-food, NODS, guns and ammo, hygiene and sanitation is very unsexy but it's critical.
