One of the things he said that struck me was that there is more oil underground in Colorado and Wyoming than in all of Saudi Arabia. That sounded pretty fantastic, but appears to be true, according to this 2007 Fortune Magazine article:
If that sounds like hyperbole, then consider this: Several hundred feet below where Vinegar is strolling lies the Green River Formation, arguably the largest unconventional oil reserve on the planet. ("Unconventional oil" encompasses oil shale, Canadian tar sands, and the extra-heavy oils of Venezuela - essentially, anything that is not just pumped to the surface.)
Spanning some 17,000 square miles across parts of Colorado, Utah and Wyoming, this underground lakebed holds at least 800 billion barrels of recoverable oil. That's triple the reserves of Saudi Arabia.
