Now, there's a quick way to find out. Get more details on today's Website of the Day after the jump.
Called Go-Gas, this website can tell you exactly how much (in gas) a trip will cost you. Using Google Maps and some quick calculations, Go Gas prompts you to enter your car's gas mileage and then your trip route, and will calculate how much your trip is going to cost you. One tip: the site works in a number of foreign countries and currencies, so be sure to set the mileage to MPG and the currency to USD if you're in the US.
