Knowing that our mail passes through the regional processing center before returning to the local area, we expect about three days if we mail a neighbor. Post offices around us have two mail slots when you walk in to drop mail in the box: local only, and everywhere else. Presumably they have (once had?) separate localized processing for those in the “local” bin. Because of post office closures and reduced hours, I think everything is just passed off to the regional facility for the last few years. Another interesting discovery: I live about 3mi from my parents. They’re over the line in another county. My post office services them, but when I still lived in their house, all our local government business (schools, taxes and whatnot) was in the county seat about 15mi further away from the serving post office, closer to the next regional facility further south. If we ever dropped mail, say from mom to her mother, in that town, it took at least an extra day because it had to hit two regionals before getting to grandmother’s local.
