Herbstwiese (Autumn Meadow) by Edward B. Gordon
The drained hatcheries are just big rectangles that were dug into the earth around 1910 and filled with water (and presumably fingerlings). These days they have been allowed to grow over and some have water (with turtles sunning themselves), some have all sorts of plants, and everything is much wilder than you have a right to expect in the heart of Dallas. The paths are kept just clear enough for walking though you still have to decide sometimes whether to go over or under huge tree trunks that have fallen.
As we expected, there were few birds since it is Autumn and they were not sitting around singing but busy migrating or eating, depending on their bent.
When we emerged, as I said, there were a few picnicking couples scattered on the well tended lawns nearby.
It was a really great way to spend Sunday.
