If you have not filled your tank up yet you better get to your favorite fill up spot...

Gas prices are said to be going up in the wake of Isaac churning his way through the Gulf.  Off shore oil platforms are being shut down and evacuated which means less supply of gas to the US market.  So if you haven't filled 'er up yet better do so in the next day or so or else you could be spending well over $50 bucks for a fill up.
