It's not your traditional Christmas tree, made with PVC pipe and adorned with wrenches, a tape measure and other tools. Yet it's one of the 30 original offerings on display this week at Three Star Mall as Wonderland of Trees celebrates its fifth season."Our trees have more variety this year than ever before," said Melinda Breedlove, who founded the event with her sister, Dianne Sneed. "People are free to donate whatever they can dream up."There are a number of unique Christmas creations on display until Saturday at the mall.
