The Treecycle in Sydney, Australia
I saw this tree and had to post the link to the site with pictures of it. It is a Christmas tree made of scrap bicycles. It looks awesome lit up but is just as impressive when its not. Something to think about for all you folks with huge yards. lol! I'd have to make one with Barbie-size bicycles for my yard. But even a tree made with old bicycle wheels might be cool too. Enjoy!
