Simply because they are so outstanding, true lights rods have also encouraged decoration. I appreciate excellent layout, so I made a decision to find lights rods with fine type. I stumbled on some hanging styles: an antique copper lightning rod with a starburst tip, a vintage lightning rod with a wind indicator from Maryville, Missouri, along with a vintage lightning rod in ornate hammered aluminum that has a cobalt-blue ball and a roof mount.
