The map actually has some pretty neat functionality. You can right-click on a specific county and pull up the average gas price. If you click on that it’ll take you to the gas prices for that whole area (here’s Orlando).
I also went ahead and created a graph showing the average price of gas in the Orlando area over the last 12 months. The red line is Orlando, the blue is the US average. (you can make your own chart for your local area here)
