Remember the fun gas map? Which, as a side note, would be really neat to see animated over the last 6 months. Does anyone know of that existing somewhere?
Anyway, this is cool too: current gas prices for Genesee county. Gives the lowest gas price in the county as of the time reported, which seems to be very recent for most of them. I think they have it for every county/state also, accessible here by right clicking on the map: gas map. Now I need to be able to plug in where I am and the size of my tank and have it tell me the gas station I need to go to get the best price factoring in distance from me and the amount of gas I need.
