i have a heated garage but my ouside vehicles, like my snowplow all must be plugged into a block heater or will not start. after about 15 below many cars wont start without an engine block heater. when you go out to eat, you leave your car running if you want it to run when you get back in.
otherwise things go normally as long as you dont have pipes on ouside walls which will freeze up your plumbing.
i still go out ice skating if not windy and do all the normal things that one would do.
humidity here is usually around 30% anyway.
