The route could be a huge loop that leads you back to the depot and there are a few larger bush properties around that area but a postie always returns to the post office to drop the undelivered items for pickup, you know when you get a card to pick up? It’s illegal for items to remain in a van overnight, it happens I know but illegal. It’s usually a tried and true route which can be changed, it’s up to the postie. The only time I changed it was when I had several huge boxes that I was happy to get rid of, maybe like Chapman’s plants that might have been in my way. There were times I delivered bees. Ah yes bees, buzzing in tubes in the back was unnerving or plants but I still usually stayed on route because then it makes for a late day. Like Chapman’s plants I would’ve put the air conditioner on. Sometimes I was found by people who needed their items & that was fine.
