Of course nobody knew about it. I can't even file my income taxes without the aid of a computer program and a book. It's the same story with the earmarked discretionary spending in transportation bills. None of the representatives could read the entire bill even if they wanted to, and so "pork" is jammed through and the tax payers are left soaked. The lesson is: if the bill is too complicated for ordinary individuals to understand, it's too complicated period.
