On the last episode of the heads of Sierra Blanca,

It was written to me anonymously, wanted me to know who he really was.

This man is telling us he could be anyone. He's clearly someone who sees a kind of meaning in his work.

Sometimes there is a greater plan at hand. I hope to create a machine that the world has never seen before, a machine with

It is undoubtedly one of the most dangerous places on the entire planet.

This is the heads of Sierra Blanca.

A recent Gallup survey shows Americans worry more about burglary than almost any other crime,

That's why Simply Safe is my top choice.
