The rational solution is to STOP! Given a choice between a known and fixed cost of cancelling HART's blunder @ $3 Billion, or an unknown or unknowable cost of continuing the rail through what would be the most expensive section to Ala Moana Center should be simple. Would it be better to put one or two more generations of Oahu taxpayers in debt to pay off and end this debacle, or to put unknown number of future generations to pay, perhaps in perpetuity for this train to penury? The choice should be obvious.
