That sounds like a crazy trip mp, coldest I've ice fished was -26 at chesterfield and it wasn't to bad, In the tent with the heater on. My track was froze up but I got it free pretty quick. Been reading some things about people quitting the tourney today and having trouble leaving, they can't keep warm enough in tents with heaters going and to top it off they're machines don't want to start to get they're stuff of the ice. Crazy cold
