 GEOG: Bringing back Sam Levine as Lt. Abrams of the San Francisco PD  from AFTER THE THIN MAN is a welcome addition to the cast. However,  a San Francisco homicide detective wouldnt have had jurisdiction at  the racetrack. The only possible area horse racetrack would have  been Berkeleys Golden Gate Fields (opened 1941), which is well  outside the San Francisco city limits and is reached by driving  across the San Francisco Oakland Bay Bridge (where Nick got his  speeding ticket and police escort to the track).
