The wife and I used to camp and fish at Ft. Cobb Lake every week during late fall through early spring. One early fall evening, we were sitting by the campfire, watching the sky for shooting stars. The wife spotted a snake in a branch of the oak tree next to us. We thought it was a strange place for a snake to be. He was still there when we went to bed.
The next day, after catching quite a few blue cats, we rowed our little aluminum rowboat to the bank (about 15' from our fire ring). As I prepared to clean the fish, that snake crawled out of the water, over the sandstone bank, to the tree, and up the trunk, to the branch, and right over the fire ring, making himself right at home.
That snake climbed up to that branch every evening every time we went there to camp. He knew right where to go, if he wanted to warm himself over our fire. We never named him, but we always looked forward to seeing our pet snake.
