One of my favorite holiday traditions: looking at Christmas lights! For my book, Merry Christmas, America! (on sale at Amazon) I toured the country and climbed up ladders with America’s best Clark Griswold’s to find out why they do what they do. I stopped by the CBS Early Show a few year’s back to talk to Harry Smith about the book and about lighting it up! Check out the video and find out why some of our neighbors go to all this effort and how they make Christmas sparkle.
