I always thought that they should do home pick up & delivery 3 days per week but adjoining regions would have different days. So region A would get mail M,W,F and region B would get mail on T,Thurs., Sat. The mail carrier would alternate between regions A and B. It seems like you could almost halve the number of mail carriers this way.
