To the doomers above- get a grip. Natural gas extraction tech is improving by the month and it will only be another 3-4 years before oil becomes irrelevant to the US. The world population just reached 7B and will explode to 8B in the decade. This is good for us because we have a near monopoly on farming science, chemicals, equipment and some the most fresh water and fertile land. The US has some juice in her left don't worry. Our currency is backed by something more relevant than gold- the military. Yes, Obama should have spent that $1T stimulus on developing natural gas tech but he's an idiotic Dem so what can you expect. Instead he orderlessly sprinkled the money all over the place thinner than November ice. He will be out of office soon enough though.
