I'd seen that picture before as it is the picture on the cover of one of my favorite Florida books, The Barefoot Mailman by Theodore Pratt.
Here's the bit which accompanied the picture on the FB post:
The murals, The Barefoot Mailman, by Stephen Dohanos. Here is Emily Bell of Fort Pierce:
"Now my husband (Jim) got the mail contract to carry the mail from Titusville (to Lake Worth then, now Palm Beach). He made a trip every two weeks. …
He would start as early as the wind would be hard enough to fill the sail. Then he had to stop at Waveland with mail to the Baker family. They were an old and fine family, who came there for health, but I never knew them very well. He had to leave his boat at the [Jupiter] lighthouse and row across to the south side, then carry the mail bags on his back, walk eight miles to the postoffice. He carried it for six months, then gave out. He said someone sent an iron stove lid in the mail and some potatoes and seeds, so he stopped. I don’t remember who, but think it was Jim Russell who took it next.
When the tide was high the sand was so soft they could hardly get along. They only got $30 a month. He would have to carry a smudge pot with him, then he would rest one day and start again. [See Capron, John]"
Yep. That's how they did in the old days. I think about that when I'm walking on the beach sometimes. I wonder how far I could go with a bag of mail on my back along with the water I needed to drink, the food, whatever bedding I might require.
Probably about fifty feet.
Someone sent a stove lid? Potatoes?
Yeah, that's asking a bit much.
Hope all of you are fine. I am. Boys coming soon. Why does walking make me so hungry?
