The World of Outlaws World Finals, called by one public relations rep the “Super Bowl of grassroots dirt track racing,” is returning this week to The Dirt Track at Charlotte Motor Speedway in Concord. It’s bringing more than 40,000 spectators from Thursday to Saturday with an estimated impact on the local economy of $8 million. John Mills, with the Cabarrus County CVB, said the festivities will bring in $5 million in direct visitor spending on hotels, food, transportation and retail stores, and another $3 million in estimated indirect and induced spending. “It’s a great event,” Mills said. “It’s a pretty big one for us, so we’re glad to have it here.” Visitors from all 50 states are coming, along with others from Canada, Australia, the Netherlands and the United Kingdom and area hotels are filling up.
