Stilly, I remember reading about one of the towns in
the "Hill Country" of Texas, to the south of you,
and I am thinking of those German-American farmers.
Was it New Braunfels?   Fredericksburg?
They had their homesteads out in the country;
they had to come to market often enough, and
of course they were church-goers,
so they would come to town on Sunday,
and didn't they have 'Sunday-cottages' or something in town,
with outdoor showers -- that's why you reminded me of them --
and just the basics for sleeping overnight or something.
Then it was back to the farm for another week of hard work.

And when times changed and the town changed and developed,
eventually there were only a few of these little sunday-houses
still standing, and now
they are the real-estate version of collector's items,
historical artifacts.
I probably scrambled this up in recalling.
