Who has the best gas prices?

As we have all been struggling to keep up with the rising gas prices, one service Internet service has been developed to help you find the lowest price in your area. That would be GasBuddy.com. GasBuddy has any easy interface (despite the busy distractions): click your state and enter your zip code - that's it.

You can also find the average price for gas in each state plus Washington DC. Here in Oregon, we're currently averaging $4.268, 45th of 51. The lowest average goes to Missouri at $3.854 and the highest goes to Hawaii at $4.552.
With the gas temperature map, you can see the range of gas prices within your state (or for the country). And finally, you can view the trend of gas prices for up to 3 cities over the last 6 years.
