The largest source of oil for the US is the US. By a very wide margin. Dharma was talking about Canada and Mexico.
As so, as I said, "Nah. We produce almost twice as much oil as those two combined, and refine God only knows how many times more gasoline...odds are its good old fashioned American gasoline. Like baseball. Or apple pie."
Thats the beginning and the end of what I'm saying here: "Odds are good."
Going to be interesting to see how things shape up in the next decade, as the US reaches energy independence.
