As in other countries, the mail must get through, no matter what the weather. In my little town, the mail delivery takes place either by Shanks Pony (in the downtown area), or from the seat of a tiny motor scooter, somewhat like a Vespa.
Here is a photo of one of our mail men, on the main street of the town.
We have to provide mail boxes on the fence line of our property: the mailman/woman doesn't come to our door. My mail box badly needs painting, so this photo shows the mailbox that belongs to one of my neighbours.
Now, where is that paint and a brush?
