content: A stolen garbage truck filled with 3 tons of stolen explosives from a mining site(s) would be pretty big and heavy. With a makeshift brush guard added to the front it could probably ram through most fences and even the side of a building into the heart of a server room. Or if parked next to the building the explosion could do QUITE a bit of damage. If you had a secondary person driving a get away car you could make a pretty speedy exit. This fictional dooms day novel you are thinking about writing sounds pretty interesting. I can't wait to read it when it gets published.
