Have you ever seen pictures of the inlays that are on the woodwork in Congress? Oil Derricks and Tobacco leaves. People still smoke yet they know that the odds are it will kill them..... it defies logic. We will continue to drive cars using oil based fuel because of the lobbyist and backroom deals. CNG is a great idea short term but long term fossil fuels aren't the answer.
Obama has all the answers, just ask him. He will have this problem solved by the end of next May. If you could just share the wealth he might have it figured out by the end of February.
