Now I'm no rocket surgeon, but how does this world have unlimited fuel, power, and people trying to kill a fungus with bullets. Helicopters are not efficient vehicles to operate. Boston is not a region known for oil refineries. Car batteries don't last 20 years. Finally, the last time I went into surgery, I didn't use bullets to sterilize the operating room. I used chemicals and pesticides. Agent Orange would do more damage to this outbreak than a gun.
