  In a number of quasi-one-dimensional organic metals the dependence of the
magnetoresistance on the direction of the magnetic field is quite different
from the predictions of Boltzmann transport theory for a Fermi liquid with a
scattering rate that is independent of momentum. We consider a model in which
there are large variations in the scattering rate over the Fermi surface. The
model is the quasi-one-dimensional version of the ``cold spots'' model
introduced by Ioffe and Millis to explain anomalous transport properties of the
metallic phase of the cuprate superconductors. The dependence of the
resistance, in the most and least conducting directions, on the direction and
magnitude of the magnetic field are calculated. The calculated
magnetoresistance has a number of properties that are quite distinct from
conventional transport theory such as magic angle effects a significant
magnetoresistance when the field and current are both in the least conducting
direction. However, the model cannot give a complete description of the unusual
properties of (TMTSF)2PF6 at pressures of 8-11 kbar.
