The thoroughbred horse Spring Racing Carnival is in full swing in the state of Victoria, Australia, culminating in the running of the Melbourne Cup, “the race that stops a nation.” Attendance at what is more akin to a “garden party” setting can well exceed 100,000 on Derby Day, Oaks Day and Melbourne Cup Day, and there are plenty of on-course bookmakers in the Betting Ring ready to offer odds to the eager punter.
