DIY: Tractor Tire Garden Pond ~ this has been floating around Facebook and now Pinterest. What a wonderful way to recycle old tires! I love this and you can use any size tires for this project. Some put fish in it too! There's quite a few instructions on this 'tire pond' idea but here's a link for detailed, pictorial instructions from another site: http://www.instructables.com/id/Fish-pond-from-tractor-or-car-tires/. Nice!
