A friend of mine posted this picture and information.

The 25-foot-tall Christmas tree made of tumbleweeds, a tradition that has been taking place in Chandler since 1957. City workers spent months collecting nearly 1,000 tumbleweeds to adorn a wire frame shaped like a tree. From there, the tumbleweeds were sprayed with 25 gallons of white paint and 20 gallons of flame retardant, then dusted with 65 pounds of glitter. They say Chandler's Tumbleweed Tree was the brainchild of Earle Barnum.

 For those of you who are not from Arizona this is what a tumbleweed looks like
