Not quite on point, but for many years the six mail boxes (all lined up in a row on a single structure) at the end of our 850' driveway, and on the highway were so close to the highway that the postal delivery person had to stop half way onto the two lane highway to deposit mail. Same risk for others who came by to pick up their mail. The structure supporting the row of boxes was old and shaky and I wanted to rebuild it. I wanted to move them back as well. I never understood why they were located so close to the highway, but figured it was because there was not much room to move them back from the highway due to the hillside.
I first went to the post office and asked if I could move the row of boxes, and if so, if I could eliminate one of the very old and unused boxes. I was told I could rebuild and move the structure, but would have to leave the old box as someone owns it.
I spent a half a day taking out the hillside, and another half a day putting in new posts and rebuilding the structure and remounting all the boxes. It turned out nicely.
Well, the next day I picked up the mail and found a note from the delivery lady. She said she was constantly scared to death delivering mail there and was so happy to be able to pull up to the boxes completely off the highway and safely deposit the mail. Later I happened to be at the boxes when she arrived and she exited the car and came over to me and thanked me again, and said the structure was the nicest one on her route. A couple of the neighbors later also thanked me as they no longer had to park across the highway and walk over to the mail boxes. Not that big of a deal for me to do this, but it sure made a lot of people happy which was gratifying.
But I suppose if someone somehow had an accident exiting from the boxes and onto the highway they would look to blame someone else for their negligence, and that would be me.
