It's dark at 4:30 in the afternoon and that can make me feel blu-ish. So I have shouted back the dark by building my own snowflake for the front of our house. It's more Cub Scout than Martha Stewart, but I like it.
A 10' section of pvc pipe, a pvc drain cover, silicone caulk, a string of lights, a couple of waste CD's and some electrical tape is the recipe for a small, stinky mess in the garage followed by a bright addition to the exterior of our home. The generic winter theme means I can keep it up long past Christmas without feeling guilty.
