And I can find stations in the US that are over $6 a gallon.
What we want to look at is the gas prices being seen by a reasonable number of people.
We can look at US average, state average, or regional average. But it's getting facetious to start picking out single stations and say, "Look, at State and Jackson I pay $5.05 which means that everyone in Chicago is getting shafted despite the fact that at State and Ohio I could pay $4.89." At that point, the difference in price isn't because of difference in the price of oil, transportation, taxes, wages, or cost of living. It's just purely the premium that can be charged that people will still go there and pay out of personal convenience. The whole point is how far do we allow things to get bent before we dismiss them.
I don't think that saying when gas is $4.51 that it's $5 gas. That's around $6-$7 difference at fill-up. And I don't think we can just sit here and cherry pick to find the prices that we want. Why can't I say that since there is a station that's $4.35 at its highest and thus we can still find gas under $5 that we never hit $5 even if it was the only station in town to be under $5?
