Would have to agree, check the scheduling before you make too many more plans. But as far as AZBuck's reservation about the Pittsburg to Chicago leg...
It was in 2001 when I travelled with Greyhound from NYC to St Paul MN, with a lay-over in Chicago. From what I remember, we left NYC at 1am, and got into Chicago early the next morning. I recall it well. One of the drivers was on the phone all the way, argueing the whole time. They were the days before talking on a hands held phone was banned.
