It has to be price jacking. A guy from CNN actually said he thinks gas prices will not change much, due to a few factors.
1. Sure after something like this happens prices of everything tend to go up, but...
2. There has not been much activity in the airlines since this happened, which means that a ton of gas is being saved, that those huge planes would normally be using.
3. New York, one of the biggest cities in the world is locked down, not much traffic, so no gas use there either.
4. Also i know it is tragic, but there are gonna be a few tens of thousand less drives in NY, due to them having been killed in the trade centers.
So we should have a large surplus of gas, and if "W" wants to be relected next time around, he better realize this and put a cap on all gas, and food stuffs.
