To all who have replied, thanks for the information. It is a mystery to me however why they wouldn't have those records. In 1970 I called and asked about buying some complete past performances of a certain horse and was tod it would be a $10.00 charge. That was when they were based in Phoenix.
It would be interesting to know from the DRF rep. how they now don't have those records. At that time they were probably on micro-fiche.
