It doesn't matter if everyone in the United States stopped buying gas on the 15th. That's how stupid a "1-day boycott" is. You have to stop using things that use gas PERIOD. You have to go for months and months to have a successful boycott (and sometimes YEARS). One day won't do shit, and I don't see how *anyone* could think otherwise. Seriously, even retarded people are not that retarded..
Seriously... it'd be like me not eating a piece of cake for a day and expecting to lose forty pounds the next day.
Want real ways to "hurt" the oil industry? Want to save money in the process? CARPOOL whenever possible. USE PUBLIC TRANSPORTATION whenever possible. USE A BICYCLE whenever possible. Not only will it save you some green, it'll also help the environment.
