and the town of Búðardalur has a population of 250, so it's probably a little easier for the local postal carrier to find people there.

during WWII. The man I worked for was from Margate, NJ near where I lived at the time. He told me the story when I interviewed for the job and told him I was from Wisconsin.

They received all of his letters just fine.

sorting mail. We loved getting the poorly addressed pieces to the right town knowing the locals had a good handle on the residents. A point of postal pride.
