Before Mark Davis talked about the Horse Racing Industry, the word “gambling” comes to my mind. After learning from his lecture I started to realize the good side of house gambling game.  House gambling game was held to help the housing industry. In the past, the housing industry was poor and had no money to run their business. If there is no house game, there will not be house industry.  House industry has been working so hard on house race. They set very strict rules for competitors. They are the main moneymaker for the of the local market. However, It is enjoyable to watch the house race. It is one of necessary entertainment event for people especially wealthy people to spend time.
