Looking at this map of the USA county by county done by gas prices is quite interesting. Some of it seems quite obvious like the red zones in New York and California but there is some interesting areas like the one gbig green area in Washington or that deep orange area in Colorado in a sea of green in their neighboring states.
So what type of area for prices are you in? My entire state is in the orange ctaegory.
