This is Phoenix. When Christmas rolls around, there's no winter wonderland, no riding in one-horse open sleighs, and no roasting chestnuts on an open fire (it's probably a no-burn day, anyway). What we've got, though, are mild evenings perfect for driving around and looking at holiday light displays, and the Moon Valley Neighborhood Association's 12 Homes of Christmas event in north central Phoenix is our favorite way to do it. The 29 subdivisions that comprise the MVNA include plenty of homeowners who go all out on the decorating front, including sound, light, and motion displays. Judges come through in early December to pick the delightful dozen, then produce a guide to the winners (along with winners in several other categories like the Spirit of Christmas award and the Santa's Helper award). Print out a map, pick up a hot cocoa (or an iced coffee, depending on the forecast), and get ready to light up the night.
