I drew this past week or so of strips in Georgia, where my family and I would fish sometimes. One time, my brother had left his fishing rod sitting in the middle of the dock, and someone said to put it where no one would step on it. I thought it would have been funny if someone had thrown it in the water (Ahh, loopholes). And a Billy strip had been created.
(I didn't actually throw it in the water. I just pondered the possibility.)
