if the oil goes thru Cushing, then i would think the price would be settled there. Most of the oil from the Bakken AND Alberta/Saskatchawan does not go thru Cushing. If you read the WSJ article you'll see reference to a small town in Minnesota. There's also another hub in a small 'cow' town in Wyoming (that's a pun that the truly enlightened will understand). There are also 2 refineries near Denver that some of the oil goes directly to. Shall I go on?
The 2nd sentence of your 2nd paragraph is what I said in my original reply to Dew.
