Shit, I read this article a month or so ago in Newsweek I believe about how the government was buying up mass quantities of oil for the purpose of having reserves. The article claimed that the mass purchasing of oil was the main factor of the rise of US gas prices and that documents pertaining to the matter where held secret as the White House had been heavily involved in the whole ordeal. Some senate representatives where trying to get the documents opened with no luck.
Now if I could only find that article online.. grr
