PS Bigbob, the cost of drilling in Alaska almost outweighs the current benefit. In order to make a profit from Alaskan oil, gas prices would have to be above $4. It is in a harsh environment, you would need special equipment to first dig through the permafrost, then prevent it from melting around your equipment (causing your expensive machinery to sink into mud).
I don't know where you got the 100 years of oil from, the last estimate I saw was it could last the state of California 3 months, if that were their sole source of oil.
Then again when you only get information from one source, you tend to not know all of the facts.
