I'm going to chime in with my observations of things I think are no big deal, having grown up in the country: 1) Fishing at night, especially catfishing is very common. In fact, many believe night is the best time for catfishing. 2) Many people know where other people's favorite fishing holes are. If someone was looking for one of them, they may know exactly where to go. The father did. 3) Bullet holes in signs are common - people use them for target practice.
