I know way too much about season ticket prices. And the price of soft drinks, beer and the cheapest adult-size cap available for purchase at a professional sports stadium.
From 2003 until early 2015, I worked for a company called Team Marketing Report, a sports business publishing firm famous for a few niche products and a fan survey called the Fan Cost Index.
The Fan Cost Index, or FCI, measures the cost to take a family of four to a sporting event, using season ticket prices and the cheapest option for food, drinks, parking and the like.
