I was very intrigued by the name, and actually a very good tip. But Sleeping Naked is Green is a book by Vanessa Farquharson. In it she takes the challenge of making one green change a day. She's a city girl just seeing if she can make a difference. It is very fun to see what worked for her and what didn't. Just like me, she is not hard-core, but unlike me, does make some very drastic changes. Very good book if you are for being green, or against it.
