For the last 2 weeks it has been cold here in western Canada warms up to -5 F then a strong wind at night down to -12 to 15 F . Life is not fun with out smoker smoke :'( :'(
I am in the same position in North Dakota. The smoker can handle getting to temp without problem. But, I just don't have the motivation to go outside and smoke in these type of temps.
Rival/Oster has a smoker toaster oven. A fellow at work has one and brings it in for pot luck. Does a fairly decent job. You can park it on your stove under your vent hood and let it rip.
