In order to prevent witnessing further gas station signage hilarity, MapQuest (remember them?) has a nifty cheap station location feature. Basically, it maps out gas stations in your neighborhood/city by price. In San Francisco there's a scant difference between the highest and lowest ranked stations. Whatever. But SFist readers way out in Whereverville -- i.e., cities where automotive discussions aren't whispered in hushed tones -- might appreciate the service. Especially if money is tight for you.

And the lowest and highest gas prices in the U.S of A as of now? The cheapest goes to Hamel, MN, with a thrifty $2.40; the highest is way over in Kailua Kona, HI, boasting a whopping $4.05. Until now, we have never heard of these two cities in our entire life.

Oh, and it also comes with a nifty gas calculator for long road trips.
