  The outflow in SDSS J030000.56+004828.0 has the highest low-ionization
metal-line column density yet reported for a broad absorption line quasar. The
absorption from different ions is also segregated as a function of velocity in
a way that can only be explained by a disk wind outflow. Furthermore, the
presence of the such large column densities of gas at the high observed outflow
velocities may be incompatible with purely radiative acceleration. MHD
contributions to the acceleration should be considered seriously.
