After the sun sets, I am firmly convinced that every cast has the possibility of making my clients, or me, a hero. Sure, there are slow periods some nights and an occasional night where the skunk will bite. How Darkness Helps Line watching is easier at night because it is at least five times more visible under a black light. My clients say their lines look like ropes. I still get a thrill when people cast for the first time with a black light on.
Daytime distractions are everywhere.
We are always looking around at something and not paying enough attention to our line, which is often hard to see anyway. At night we can see our line perfectly, and there are few distractions. Other than first light, it is difficult to sustain that confidence and focus all day long, even in the spring. This is not a problem at night. I might add that a typical night trip would include the last hour of light.
