Yeah im sure they know... being they aquire the mining dynamite yearly through their occupation. They are liscened in explosives. Which is in that field. These are not just "stupid drugtrafficers" this is timothy mcvay types. These are people who work right beside you and you wouldnt know. They are your teachers, cops, builders, truckers, farmers. Along with trucking which coverd the "large bulky transport". The truck thing i mentioned before. All that shit is covered. Its way easier and smarter accumulating what one already has on hand in ecxess bulk, fertilizers, dynamite, jet fuel and has the liscence to transport.
