First belt drop hits around 6:20 a.m. and I’m staring at 118 stops with 5 oversized boxes already rolling. If I try to wing it, I’m hunting for packages at every door. So before I roll out, I split the shelves with blue painter’s tape by route chunks, then toss smalls into 3 totes labeled by street clusters (Oak/Pine/Maple). I use a fat Sharpie to write the stop number big on the short side of each box so the label faces me when I grab. One watch-out: multi-piece shipments. I rubber-band the labels together and keep them low so nothing rides solo to the wrong porch. Heavy stuff stays on the floor near the rear, and business stops that close by noon ride up front by the side door.
