US Gasoline Price Watch
I was just thinking the other day that, as gas prices continue to rise, it would be great to have a web site that listed all the current gasoline prices for your area. I played around with a very simple database but a quick Google search turned up someone who has already put together an excellent site. You can even join up and be a price spotter for your area. If enough people updated the prices this information could be quite useful.
From the web site
