This is an image you don't see here in Atlanta: clothes hanging out to dry.
Here, clothes dyers are a "bare necessity" and also a major energy consumption, not to mention a source of house fires. I do recognize that sometimes it comes in handy, but this is Georgia, with sunny weather most of the year. In Portugal hanging out your clothes to dry is a cultural thing!
We've been trying to be sustainable in small daily things and buying this rack (on craigslist of course!) is just another step towards a more eco-friendly life. Aside from air drying our clothes, we've been using biodegradable laundry and cleaning detergents. They cost a bit more, (but not a lot more) and in the long term are better on the environment and on more gentle on our clothes.
