There is no question that the team now running the event, Race On LLC, is more impressive than any that have come before it. The local investors who are bankrolling the event have partnered with Andretti Motorsports, a firm that has extensive experience in putting together street races like this one. The race's general manager, Timothy A. Mayer, has been living in downtown Baltimore for the last several weeks and meeting with business owners, city officials and others in an effort to avoid a repeat of the problems large and small from last year's race. He has tweaked the course, the grandstands and fences and overhauled the management structure of the event in ways that should make it an even more enjoyable event for race fans. Mr. Mayer said putting on a race is a matter of thousands of tiny details, and he is clearly in command of them.
