- CAChristiaan AdamsJan 8, 20185.0Wonderful small-town post office, with super friendly and helpful staff. This place is reported by the USPS as being the second oldest continuously-operated post office in the country, having been in the same building since 1833. Wish our big city post offices could be as pleasant as this one.
