You say...."The project was paid for nearly in its entirety by Federal and State grants." 
Could you tell me where the federal and state governments got that grant money?
Borrowed from the Chinese? 
Taxes collected from the governed (that's you and me. Or at least me, I don't know if you pay taxes or not)? 
Printed more money, as Nothing but the truth suggests?
There's a lot of things I don't mind my tax dollars being spent on, but big, mostly empty buses are not one of those things.
