I don't think so. The trick can be getting your grill up to temp when you have single digit temps. But, once you're up to temp, they don't take that long to cook.
Looks like pointandshoot and I live in the same town. We got about 6" of snow on inauguration day. The kids loved it. Still on the ground but thankfully off the roads. We just dont keep many snow plows in reserve in these parts.
