The people who run Louisville's new downtown arena say there haven't been any major problems with traffic and parking during its first month of operation. Arena Authority Chairman Jim Host says it appears most people who have attended concerts and athletic events at the KFC YUM! Center found a suitable parking spot near the site."I think what's happened is that a lot of people have figured out that you can park two or three blocks from the arena and walk, and that's what people are doing...the arena garage hasn't been totally full yet," he said.Host also credits Louisville Metro Police with keeping traffic moving, even when there are events at nearby venues such as the Kentucky Center and Actor's Theatre.
