I'm pretty sure the question has been addressed here several times but I've been off the internet too much to have ever seen it so...Could someone explain how PAS works? We are getting it next year. I've talked to drivers from the hub over from ours and from what I've gathered it is going to be like all the stops are prerecorded in the diad and the driver just needs to find each package in the section it is "SUPPOSED" to be loaded in. I am mainly interested in knowing everyone's (those of you that have PAS) opinion on it. What are the good things and bad things about it?
