In order to prevent witnessing further gas station signage hilarity, MapQuest (remember them?) has a nifty cheap station location feature.

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......
