Bianconi couldn't fill the open. So he called and offered bomber a check for shipping and lodging so he would race his 2 horses in the open and the race would fill.
As grandstand said. It's ok until people get sick and tired of being sick and tired. Seems to me some of the trainers with open horses don't want to race agai st the nobles for 3rd place money. So bomber is getting g paid to bring some horses
