I have a few questions? We are driving Thursday from Valparaiso, IN to a park and ride on West 47th near Midway. In your oopinion what is the best directions to drive there? Also we have to be there at 5:30 a.m. What time do we need to leave home? I know I hear on our local radio all the time about the traffic delays but will there be that much traffic that early? Thanks so much for your help.
