Time is running out to submit your entry for our "Unexpected Green" Contest - tomorrow is the last day we will accept entries. So, if you have found "green" objects in surprising (and traditionally un-green) places, send them to us at: contest [at] treehugger [dot] com. We will put the top entries on the site, and the winning entry will be chosen by our esteemed readers. The winner will come away with a $350 gift certificate from our friends at Earth, makers of the Negative Heel shoe. So, if you want your chance at some cool Earth gear, send your entry to us by tomorrow.
