Also the trainers are far more flexible when it comes to the rates they charge owners. Unlike a lot of their thoroughbred counterparts, harness trainers are open to training on a percentage of prize money earned basis instead of a flat X amount of dollars per day.
Its a shame thay they didnt touch on the funny/shady business aspect, but that side of the business seems to be well known, yet never discussed. It is a fun sport ( shady business aside ) and appeals more to the average punter with its reasonable costs and low expectations.
