Gassing up isn't cheap: According to AAA, we're now paying a nationwide average of $2.73 for a gallon of regular. That's about 25 cents a gallon more than last year. But it's certainly better than the year before, when prices shot up to over $4/gallon.

But if the cost of gas bothers you, be happy you don't live in Asmara, Eritrea. This African nation boasts the highest gas prices in the world — nearly $10/gallon. On the other hand, you could be living in Venezuela, where prices are as low as 6 cents.
