Pollard said of Lightning Bar that "I always had to be careful about the kind of latch I used on a gate with that horse. He could figure them out faster than I could. He would open a gate, and go for a stroll." Lightning Bar sired 148 foals in his eight breeding seasons. 118 of those foals went on to either race or show careers. 108 of his foals started races, and 77 of them won races, with a total of $476,949 total earnings.
