Mark Davis guest lectured to our class about the livestock industry. From his presentation I learned a lot about the horse racing industry and horse racing in Delaware. Horse Racing is one of the oldest sports, beginning in the 12th century. Currently, there are 9.2 million horses in the United States and 2 million people own horses. Some horses are for showing, racing, recreation, and other. Most horses are for recreation. Harrington Raceway is the oldest continuously operating harness racing track in the country. Harness Racing has about 145 days per year yielding about 2,000 races.
