Caddo Parish has achieved a "first" -- the first governmental entity in the state to receive a AAA bond rating from Standard and Poors. What's that mean for the citizens of the parish? Bond Attorney Grant Schlueter says the AAA rating will mean that the parish will be able to get the lowest interest rate possible on its bonds. The timing could not have been better since the parish plans to sell $6-million worth of library improvement bonds tomorrow afternoon.
