Here's how to have a good time at Emerald Downs: If you can swing it, bring $40 and plan to lose it all. Start placing tiny bets—put down a buck or two on the horse with the best odds to show (meaning to win first, second, or third)—and you'll start to get the hang of the esoteric wagering process. In the meantime, enjoy the carnival-like atmosphere. Eat something deep-fried. Admire the fancy hats on the ladies. Take in the weirdness that is very wealthy and very poor people standing elbow-to-elbow, stamping their feet, and cheering for the same horse.
