These cold days are great for trout too!
The biggest issue I have with fishing in these bitter temps is stuff tends to break really easy and a simple fishing trip can get real expensive fast! I’ve seen numerous heaters go, trucks/snowmobiles not start, axels break on trailers, transmission lines break on trucks, fish house windows crack and break. The list is endless. But once I get to my spot and set up, temps don’t really matter because I’m usually a sweaty mess anyway.
Bingo. Just ain’t worth it IMO
