DEAR HARRY: I was browsing on my computer the other night when I came across an article that claimed that the U.S. has oil reserves in a belt from Montana to Texas that exceed those of the entire Middle East. The estimates run to a trillion barrels. This is supposed to be a long-held secret by an agreement among the major oil-drilling companies. The article seemed to be the real McCoy, with all kinds of backup information. It also urged readers to sell their oil-company stocks and get involved in buying long-term oil options. Could you please find out if these reserves really exist?
