Well the deep freeze is on all of a sudden. It's been unusually warm this last few months in Winnipeg but now it's back to normal for a bit. -25 tonight and it feels like -28. Brrr. Slapped on a quick cardboard grille block for the lower grille so that it's all completely blocked. Warm up is the same as fall temps without overheating in the city. Bonus! I have to turn down the heat on the highway. Bonus!
