I have never understood why people do it. I think I'm a bit over-decorated with a holly wreath on my front door.
A neighbour, just round the corner from me, has an enormous load of illuminations in the front garden and on the roof (it's a bungalow). Some of the structures are left out all year round (only lit at Xmas) but each year they add more than ever. Most of them are white but, this year, they have added bright blue lights as well. I bet you can see the glow from Space.
