The subject of cosmic ray origin is frequently treated as though it were a complete mystery. This is true for the highest-energy cosmic rays -- those exceeding 1018 eV. While these are of great interest, they comprise a tiny fraction of the cosmic ray nuclei arriving at Earth. For the cosmic rays with the highest intensity (flux), the connection with supernova shocks has been cogently argued for a half-century, by V.L. Ginzburg and others. Evidence for this is reviewed.
