A three-year renovation of the Louisville Slugger Museum and Factory in downtown Louisville is complete.At a ribbon-cutting ceremony Tuesday, company President John Hillerich said the renovations cost a significant amount of money, and were paid for entirely by the company.Hillerich could not give a timeframe for how long it will take the company to see a return on the investment. He says it depends on a number of outside factors."What helps boost visitors is when Louisville as a whole does well," he says. "When Louisville does a nice job attracting conventions or visitors, that's when our attendance goes up. A good example is this FFA. When they're in town we just do a huge amount of business."Hillerich says the museum has not seen a significant decline in visitors in the current economy.
