If you ever wondered what your local neighborhood gas prices are, maybe GasBuddy can help you out. The site is ” the portal site to more than 170 web sites that help consumers find cheap gas prices.” Using a map system and a local database of gas prices for thousands of cities and towns in the US and Canada, this might be one of the more useful mapping projects I’ve come across. Just enter your zip code and your local prices with maps and addresses of stations are listed. This could be very relevant to motorists in California where the gas prices are rising to $4 a gallon in some places.
