Been watching the PA Farm Show on TV this week. One of the things they show is Information (propaganda) displays by various government agencies and trade groups. The representative/spokesman/explainer for the Marcellus Gas group, while explaining to the crowd how fracking works, looked me right in the camera and said the 
only thing they put down the well is water and sand.
Now how am I to trust these people after they try to blow that smoke up my ass?
