I saw some people fishing the other day in 16 degree Fahrenheit (-9 Celsius) weather at 4:30AM. They were not ice fishing with a little hut, but standing at the base of a bridge with no shelter or campfire. People are at that bridge fishing regularly when it is cold but that was the coldest temp I have seen so far. Why is it so appealing to them?
I was fly fishing once and came across a school of some tiny little fish that hit basically anything I threw at them, and then fought like they were a big largemouth, especially with a fly rod. I stayed there catching and fighting them for a good hour before they got tired and swam off.
I think they were having fun, too because none of them swallowed the hook, just nice and clean through the lip.
Sounds like some kind of sunfish
