Jim – I passed a convoy of olive drab unmarked 40 foot tractor trailers each with four 10 yard ammo bunker boxes chained to them and unmarked armored Hum-Vee’s heading north on I-95 in Brevard County, Florida this past Thursday morning. The “govt” is positioning these ammo storage boxes, I have been told, in strategic places in population centers around the country. They are usually painted olive drab and are unmarked except for indistinguishable numbers/letters probably for inventory,
