Living in MI, I'm not confined to the house when the temps get cold. Like MN and OH, it got down to the -20's with the windchill Sunday and Monday. I still leave the house to go to work or run errands.

Kia loves to be out in it, but I'm finding the Chipper doesn't like to be out for longer than 15 minutes. He starts to cry and hop from foot to foot, so we've been keeping trips outside short.

I love snow and playing in it, but don't care for the single digits and the negative windchill numbers.

Like everyone else, I just let the car run longer before driving off to give the engine time to properly warm up. I've never had to plug any of my cars in though.
