Where does the money go?

Several months ago, Pittsburgh's Port Authority and Philadelphia'a SEPTA were in crisis. Fare increases and service cutbacks were imminent. Consumers of public transportation stormed to Harrisburg (on busses, of course), to demand dedicated funding for the embattled transit agencies. Then, at the last minute, Governor Rendell found $35 million sitting in some highway trust fund that he was able to divert. This may have been the right thing to do, but it does make one wonder about how many other pots of money there are out there, and whether or not our government can be trusted to spend that money for its intended uses.
Now Pennsylvania voters are being asked to approve a $650 million bond issue to fund unspecified environmental needs. Hmmmmmm.
