John,
You are so correct.."Little did we know"..I remember cheering when Chris Amon came around at the 1968 NZGP and Jim Clark was not in sight. We were so spoilt then with quality of drivers in the Tasman Series, we just thought they would all be back again.
I think that was also the last time that Bruce McLaren raced at Pukekohe.
"Little did we know " indeed.
