Jeff Greenhill liked horse racing so much that he quit his job as a successful chemical engineer at age 41 to plunge headfirst into the game. Some 16 years later, Greenhill is still having a good time, although nothing has come very easy for him and his wife, Sherri.
Greenhill, 57, takes it upon himself to van the horses he and Sherri own to a variety of racing venues from their base in Kentucky.
