Does money talk?

Tomorrow is Not One Damn Dime Day. The premise is not to spend any money for 24 hours in a boycott of sorts to speak out about our displeasure in Bush and the way he's handled the situation in Iraq. From their website:

On "Not One Damn Dime Day" those who oppose what is happening in our name in Iraq can speak up with a 24-hour national boycott of all forms of consumer spending.

During "Not One Damn Dime Day" please don't spend money, and don't use your credit card. Not one damn dime for gasoline. Not one damn dime for necessities or for impulse purchases. Nor toll/cab/bus or train ride money exchanges. Not one damn dime for anything for 24 hours.

Will anyone take notice if enough people participate?
