We're just a touch over $4. USD for 87 octane here in Kingman, Arizona.

If I remember the figures from tonights newscast correctly, taxes on one gallon of gasoline are just under a dollar.

Fwiw - my little brother used to work in the oil industry and about 15 years ago they were saying within the industry that at the present rate of use, the US had a 2000 year supply of natural gas.
Plus, it runs cleaner and creates less smog.

Have to talk to one of those multi-million dollar pay oil co. CEOs to find out why we're not running natural gas in our cars.

And, there are some scientists who think that the earth has more oil than is said.
It tends to replenish itself albeit slowly, but there are some oil fields that were considered dry or economically unviable that are pumping oil once again.

The Abotic Oil theory if I remember correcty.
