Think size doesn't matter? Don't tell that to Todd Ducote and his coworkers at Kojis & Sons Signs in Bunkie, Louisiana. They're constructing a 112-foot-high replica of an electric guitar—the world's largest. Boasting nearly a mile of neon lighting powered by 100 12,000-volt transformers, this behemoth rests on 12 concrete piles that burrow 90 feet below ground. Constructed on a steel frame and wrapped in a 1/8" aluminum skin, this Hard Rock Casino sign weighs more than 33 tons. Now that's heavy metal.
