In my life Christmas time officially arrives not when I've started shopping or wrapping, but once we've visited a very special house in our town. You have not seen Christmas lights until you've seen this house. This year I only had my phone camera, so the image is fuzzy, but I think you'll get the idea.
Each year this family adds new elements to the house, garage, yard, patio, veranda, the trees, the roof (well, you get the idea). They have blow up figures, many free-standing Santas, a plastic life-size nativity scene, and so many lights it takes the guy three weeks to put it all up. And, he takes it all down every year. Our trolley "lights tour" has him as their highlight.
It's funny, my family (and my dad in particular) is not really into outside Christmas decorations. But, we love this house. We go at least once a year, hang out with the owners and chat about the lights, what's been added, etc. What I think is one of the most wonderful things about it is that it's in one of our poorest Latino neighborhoods and all sorts of people come together to hang out and meet-and-greet one another each year.
