CSG has no proven safe extraction method. I have worked for a Multinational Oil Co. they are basically ruthless in their persuit of the $. Ethics? what's that? I am a Nat. Voter, an ex Farmer(out West), ex Stock & Station Agent. I have a passion for our country. We all have a dash of "Green" in us, I am not a radical Green, but this CSG from my research is crazy. Fatty Obarrel needs to get the message loud & clear, Stop the CSG, or have it in your very own personal backyard fella!
