We're not sure: Is it that the trees in downtown Glendale are strung with 1.6 million twinkly Christmas lights? Or is it the fact that we can shop late surrounded by bustling holiday crowds? Is it the carolers? The rows and rows of outdoor yuletide vendors? The guy selling hot chestnuts? Oh, probably, it's all of the above that makes our annual trek to Glendale Glitters such a special part of our holiday season. We like it so much that we sometimes make a second trip — easy to do, given that Glendale Glitters commences the day after Thanksgiving and doesn't close up shop until after the New Year.
