Gas Buddy has an interesting map called the USA National Gas Temperature Map. The map shows what gas prices are like around the country with the darker greens being the cheapest and the oranges and reds indicating where gas prices are the most expensive. A quick look at the map shows that prices are highest out west, especially in California. There are also high prices on the Northeast coast and in Southern Florida. What's really great about the map is that you can zoom in to focus on specific locations. If you want local prices in Chicago simply grab the map and move Chicago onto the center of the screen and zoom in. You will quickly notice there are some dark orange high prices surrounding the city of Chicago. If you right click on the map it will tell you the local average gas price. The map is a service of GasBuddy.com, which offers search tools and price data to help people quickly find low gas prices in their zip code.
