Phx seems to be the grand location. At lease thats where I have noticed thats where most of the problems tend to come from.
So much of ones experience is based on the terminal they get. In a way it drives me crazy because I have had a decent experience at Knight.
But then again there is always two sides to every story, this forum you only ever hear one side of the problem and never really know if the driver was the cause of his own issues or not.
