It so happened that we were close enough to a route and they added us. We now have three of us on the street and another was planning on doing it also.
Get oline with the US Post Office and do some reading and maybe you can do this. We had to talk to the PO of town near us as they were the ones that delivered to our area and a friend on further in town was delivered by yet another town. All our mail goes to the town we live in and then the Rural carriers pick it up.
