Hi All. I just finished reading about 20-30 posts here and I am pretty well convinced on buying the EGG tomorrow but was concerned about cooking in the colder temperatures. My propane is gutless even at 0C.(32F) I do a lot of open fire cooking at my cottage over the pit and there is nothing like it. I am hoping that the EGG will do that for me in the city where it goes down below -44C. No fear of it cracking at those temps?
