It's a nice thought Jim. However, does that mean that more people will just be buying gas on the days surrounding today (ex. "I gotta fill up my car today b/c tomorrow is 'no gas day'") I think to truely be effective at maintaining a little control over the market from the "demand" side, many americans would have to change their lifestyle when it comes to consuming fuel and I'm not sure that many are willing to do that ( I think some have probably changed to a small degree).

I think a better idea would be to try to exercise control from the supply side. that is...put every decision making oil exec up against the wall and open fire, then every american also get a chance to punch Bush and Cheney as hard as they can in the stomach, and every other top Goobermint official w/ big oil interests. It sucks.
just an opinion
