Scarce and popular Saddle Racing simulation. I'm uncertain of the first year of publication, but probably late '70's. Card sets exist through the '80s from APBA, and beyond for aftermarket. Classic horses sets are out there as well.
APBA allows replay of famous races and construction of fantasy match-ups as well. Like it's APBA brethren, statistics for each horse are represented on cards, sometimes several for each horse (for different racing years).
