When will Big Sister start buying up the total explosive production of the world and stockpiling it?
Judging by the explosives used in the recent Boston Bombings your standard, over-the-counter “fireworks” are great sources for explosives (Gun powder).
Here in Wisconsin there is a fireworks sales store at almost EVERY interstate highway exchange. Now that is one hell of a lot of fireworks stands with TONS of inventory just waiting the be blown up.
I would bet there is more powder in those stores than the gubmint Forest Service ever thought of stockpiling.
