PAS will be hard to do in Massachusetts on Saturday.
All buildings( South Boston, Somerville, Watertown, Norwood, Worcester, Chelmsford, Lynfield, Brockton,Cape Cod) send between 1-5 cars to UPS Logan Airport Building for a unload .Here each driver is in charge of what is loaded, mostly by towns or zipcodes. Then each car either returns to its own building to unload , or to meet other drivers somewhere, or leaves to start delivering .
Only the cars that return to their buildings would be able to be PAS. But again all cars are loaded by their drivers ( mostly only air drivers ) by town or zip codes. And in my building drivers can use only P700, P500 or P320 for Saturday work, that entails everyone finding their car and moving it to the one belt that is working. Many days the shuttle from Logan gets back before most drivers arrive . So the work is piled up until they show up.( if they show up ) Then after the sort is done we find out who is heavy & who is not , then its time to shift people and / or parcels around.
