Who said you couldn’t fish when the temperature was below freezing? We started at 16° temperatures. Layered up and ready to go. We had to soak our poles in the river just to cast to avoid freezing temperatures. But it was worth it. We found a spot along the river that held fish that were willing biters. Admittedly it was really cold. We ended up with eight fish that were between 15 and 20 inches.
