On the otherhand, for 5 years I lived on a fish hatchery at the end of 9 miles of dirt road. Even the local town did not have door-to-door mail delivery. It would baffle the minds of catalogue company people that my house did not have a street address, nor a zip code - as that was based on MAIL delivery, which I did not have. I would use my Post Office box (town) address zip code just to keep from confusing them. The delivery driver was a local guy - and as I worked in town, he'd often check if I was going straight home, and could I please take the hatchery's packages too? (especially in the winter)

Getting mail at the Post Office in rural towns is often a social gathering. Or a weeding out of the new folks from the older residents when signs appear on the door - "mail is late due to the snow storm, the truck hasn't made it up the mountain yet."
