We are still fortunate in the US.I am travelling in Germany,diesel is around $5.50 to 6.00 a gallon.
I do notice the highest gas prices are in the inner city areas. I suppose they figure most of the drivers don't travel all that much and don't have an opportunity to buy gas at a cheaper station. I really have no idea why gas prices are generally 10 to 20 cents higher in my area. Even Sam's Club and Costco are higher than the ones on the other side of the metro.
