Mh. Raydon Labs - are they involved in fracking? Like: do they provide the chemical coktail fracking corporations use to dig into the earth and especially to excavate the natural gases far down in the earth?
Now, what if the chemical substances provided by Raydon Labs interacted with natural gases or reactivated some substances from the dinosaur-times, and the shit came back to the surface and started to turn people around? We should not forget: It all started with an explosion of sorts, which caught Michael's attention in #1-1, So, what if a fracking station in/ at Ground Zero has just gone "booooooooom"? But I think, not even in the USA fracking would be possible right in the middle of a town, or is it???

Just thoughts. Fracking as a source or a component in the source of the zombocalypse came to my mind yesterday; and Raydon Labs sound like a company doing shit with chemical stuff - and sometimes you need this shit for fracking ...

Ah, just wild thoughts ...
