It does get kinda cold up here in NY so I went out and bought a welding blanket. I also picked up some spring clamps, carabiners and even some strong magnets to hold the blanket on the smoker. I'm just a little concerned about covering the side vents on the smoker. Will this cause a problem with the flame? I think it'll be ok, BUT I'd rather hear what you all think. My only other thoughts would be to wrap the blanket so it sits above the side vents, or cut two large holes in the blanket to accommodate the vents.
