Christmas lights have been a tradition for so long, it’s hard to imagine December without them. We heard a rumor that Denver was the birthplace of these magical twinkling bulbs — so we called up Colorado history expert Dr. William Wei to find out more. Guest host Avery Lill chats with Dr. Wei about his latest book, Becoming Colorado, which traces the state’s history using the backstories of one hundred objects, including a box of Christmas lights. We also went on a mission to find the folks behind the brilliant light displays at Denver’s City and County Building and connected with Nate, Madeline, and Heidi Webb . The Webbs have run their event lighting company Blazen Illuminations in Colorado for more than two decades and they share the secrets to what makes those holiday light shows so fun to watch.
