Duct tape buying is a small baby-step toward buying ammunition, kerosene heater, a damn fine knife, a pair of binoculars, road flares, trip wire, wood stoves, bungee cords, home canning supplies, a good axe, and a good guard dog that would make James Carville look passive.
Let's toast the meek who may take the first baby-step toward awareness by purchasing duct tape this weekend. Maybe soon they will be taking self defense classes and shooting school training. If they do that, then they will know what the duct tape and visqueen is for.....
You are forgetting the most important step for survival. John 3:16.
