I suppose Bombay has something to do with it, too. I mean the terrorist attack in India, but I don't know how to spell the city's shiny new (old) name. :)
I should probably get all miffed, and fabricate a conspiracy theory, to make myself feel better about it all.
But surr-iously, I can't relate to these people that get suspicious about different stations having different prices. I guess it's because I've been living too close to the city for too long. The station right down the street from me is always ten to fifteen cents higher than the other stations in my hood. I presume that is because it is right where people are coming out of the terminal at Lambert Airport, and it is surrounded by rental car lots, long-term parking lots, and hotels. I've noticed that the gas is usually a little cheaper near U of MO, St. Louis, and in the neighborhood where my wife used to live. Both are a little east of me (closer to the city). It's always more expensive at a certain spot I used to go, further east. Then if I go an hour to the west, by my parents' place, it's sometimes ten cents cheaper; sometimes not.
