Where's a free secret place to park in Newark not too far from Penn Station?

Question

We want to park near Newark Penn Station and take the Path Train in to 33rd Street. Any ideas?

Answer 1

Secret? That would imply that no one knows about it, so logically, no one here can answer your question.

Answer 2

I parked in the Hilton's garage, across the street from Newark Penn Station, and convinced the parking agent to give me a free day - basically 2 days for the price of 1 at a savings of $30.  There is no free on-street parking in Newark anywhere near the Train Station.
