Hanging out clothes in winter?

I know people who do it! And they don't live near the equator. I am intrigued...

I air dry a few things in my laundry room, but I would love to find a way to line-dry in winter. No fair hanging clothes all over the house; even if my husband didn't throw a tantrum, the kids and cats would get them dirty before they could even be worn.

The garage is out, too. I took a can of peaches out of there this weekend and they were frozen.

We have seven people in my house right now, which is a good excuse NOT to hang clothes out (or in) and a great reason TO do it as well.
