This. It is required for the box to be in a safe and serviceable location. Ask the Postmaster to come out and show you where. I used to be Postmaster in Ada. Years ago we refused to allow a customer to place a box at a dangerous spot just over a blind hill. He complained all the way to DC to no avail. A month later he was killed while turning into his drive at the same hill. Many times the customer doesn’t think about things like this. I suspect that might change if they had to deliver over 400 boxes a day from the right side of their vehicle.I'd go in and ask the post master in person what is wrong with the current location? Maybe have him come out and show you.
