This isn't Cotati!  Website visitor Jim Cordero pointed out that this pages and the following three pages were actually shot at Vaca Valley Raceway.  Note the embankment on outfield side of main straight:  Cotati was FLAT!  Your webmaster should have noticed this!!!  (Note:  Your webmaster shot the linked Jerry Grant photo from about the same spot as the spectators shown here.)

Prominent SF SCCA racer Brizard was a fixture at NorCal races in his lime green Elite, but he's shown in the programs of both Cotati and Vaca Valley Raceway as #85.  Neither Lotus Elite #391 nor the #282 MGA appear anywhere in the lists of either program.

There was another Class "D" Production "Stage II" Lotus Elite entered at both Cotati and Vaca Valley, it was driven by Bob Ward as #29. 

A third Lotus Elite, a Class "E" Production "Stage I" car, was entered and driven by Ted Jackson at Cotati on July 15-16 as #109, at Vaca Valley on August 19-20 as #115, and at Reno as #188.  So #391 is still a "Mystery Car".

This photo was shot at the Vaca Valley Start/Finish line on the main straight, from the infield side.
