This could be something the Liberty Groups could spearhead, with your help, to hold our local government accountable (where we have more influence).
From the document under "THE DOCUMENTS YOU WILL NEED" section:
"Check Register: The most important financial document to review and analyze initially is not the budget, but the check register. No tax dollars can be spent unless a check is written, and it is listed in a check register. Each check entry should show its number, the recipient, dollar amount, the invoice number or warrant, and reference that tracks the check to a specific line item. If a check register does not show all of this information, then it can be assumed there is something to hide."
