Here's a family that's taking "urban gardening" about as far as it can go --
http://urbanhomestead.org/journal/We're doing a lot of those things too, but nobody knows about us :)
It's funny to me that whenever someone else does things like "fewer showers", "no beauty products", etc. it's worthy of CNN.com. We just do it as part of our normal lifestyle, not to show off or make a statement.
Then again, someone has to be an example for all the wasteful people out there. My wife and I are too shy to put ourselves in the spotlight.
I should also point out ("rant" if you will) -- no central heat/AC is no big feat if you live in California. It's 75 degrees there in the summer, maybe 65 degrees in the winter *grin* Seriously, they don't have any temperature extremes.
I'd like to see them not use AC in Texas when it's 95 (or more) in the summer -- all 6 months of it -- and when it only goes "down" to 73 at night, with 97 percent humidity. "Open the windows at night and close them in the morning" doesn't work here -- I've tried.
