Post office is in a cool older building. Like any other post office there are times when staffing is lacking.

Our regular mailman is great. Thank you, Brian. Liz from the post office called me at 7:30 pm on NYE to try to sort out an issue. She could see who shipped the missing package, and I was able to confirm we got it.
