If you’re interested in how your tax dollar is being spent at the local level, check out Open The Books, a project of American Transparency. It was founded by Adam Andrzejewski as a "national rallying cry for transparency in public spending." The mission of this project is to "engage, educate and empower citizens to demand transparent, accountable and smart government across America. If you are one of the tens of thousands from all walks of life who believe in the same principles, we are here to help."
