It was the first day of hunting season one year. I don't think it was deer season; I think it was duck season. But, the deer didn't know that. They just knew they did't like the sound of loud guns going off.
There was a light fog on the water. I spotted three deer a little ways down river swimming across headed for the marsh on the other side. In there, they instinctively knew they would be safe from the hunters.
It is amazing to me that they can swim with their slender legs. While the deer are rather diminutive, they are a reference that allows you to realize just how tall the grasses are. When they reached the other side, the slipped into the tall marsh grass and disappeared, probably spending the day bedded down somewhere in the interior.
