Want cheap gas? Move to Wyoming

This post comes from Lynn Mucken at MSN Money.

You just shoved 16 gallons into your Subaru in San Diego this morning, spending $62 in about three minutes. How do you stack up with the rest of the United States -- or even the world -- when it comes to paying for gasoline?

Well, in Casper, Wyo., where gas is $3.07 a gallon instead of the $3.93 it is in San Diego, that fill-up would have been "only" $49. Of course, the temperature will be 75 in Southern California this afternoon, but just 41 in high-altitude Wyoming, so it might be worth the extra $13. Post continues after video.

According to AAA's Daily Fuel Gauge Report, Wyoming, at an average of $3.22, had the lowest gas prices in the U.S. on March 9, just a penny less than Montana. The highest:  Hawaii at $3.93 and California at $3.92. Generally speaking, the Mountain states have the lowest prices, followed by the Midwest and South, with the highest prices in the Northeast and West Coast.

Of course, if you have ever paid attention while driving around, you know that prices vary by neighborhood and location. Lower-income areas: lower prices. Last stop before the freeway: pay through the nose. It's supply and demand.

So, if you're feeling morose about what you are paying, check out The Wall Street Journal's Driver's Seat blog, which this week asked readers from around the world to report what they were spending.

If you're really inclined to beat your head against a wall, note that the average price in Venezuela is 12 cents and in Iran 33 cents, nations where the governments subsidize gasoline. Of course, there are tradeoffs there that might diminish the value of the bargain.

And, at last, just to make you feel a bit better: Two days ago, gas was $8.42 a gallon in Liverpool and $8.25 in northern Bavaria, Germany (gas is heavily taxed in Europe).
