And I think it's going to occur here, in Houston. Taking out our petrol industry would not only cripple the economy, but would make a strong point regarding the oil trade, as AQ thinks thats all the WOT is about.
Any major seaport would be horrendous. In Houston, they could cut off a lot of oil, sure, but other ports have scarier things being shipped in and out of major cities. The kind of stuff that could cause illness or death for a large number of the population.
