I live in Sault Ste. Marie, Michigan, near the shores of Lake Superior, Lake Huron, and Lake Michigan. We average about 150 inches of snow a winter, and temperatures are usually in the low teens to mid twenties, Fahrenheit, but sometimes dipping below -20'F. I maintain a pathway through the snow in our front yard and a circle big enough to allow me to easily walk around the grill. Since the winds come from the west, I build a 6 to 7 foot wall of snow on the west side of the circle to create a windbreak. And yeh, I grill all year round. That picture of a Webber covered in snow, that's my Webber. The only thing you have to watch for is to adapt to the colder air, as if snow is falling on a sizzling steak, or you're trying to cook low and slow, you have to be a little more creative to get proper results.
