I'm a BIG fan of USPS. Simply the fact that you can send a letter between any two US addresses for forty-something cents is amazing. If it goes private they won't go to or from every address and it will cost nine dollars, if we're lucky.
I'm relatively sure your could put mine and Ruth's first names on an envelope along with the name of out town and we'd get it. Lord knows we've gotten mail with half that information wrong plenty of times.
