Heat can affect people, including inspiring poetry. A haiku:
The sun takes its toll.
Dip your thermometer; look.
Fish another day.
[I didn't have a photo that corresponds.]
Maybe search for (what will assuredly turn out to be hallucinations of) Benicio Del Toro, or patronize the nearest brewery. Switch to your Type 10 sinking line and fish an impoundment, or lay in a field and let the sunshine take you to an Arcadia where trout serve you Manhattans as you wax philosophic with them. Or keep fishing, but consider your impact on our quarry.
