Your webmaster doesn't know if this Turn 6 photo was shot at Riverside during the support race for the October 14-15, 1961 "L.A. Times Grand Prix" or at the March 3-4, 1962 SCCA races.

At the March, 1962, event Spencer was 13th o.a. on Saturday and 11th o.a. on Sunday.  He won Class "C" Production both days.

Does anyone know who's driving the NSU?  The car doesn't appear in the race programs for either event mentioned above.
