I have to say it does seem odd that on the one hand there is the 'global warming' issue that some people believe is due to CO2 emissions from using more power than required from coal fired power stations etc., yet then on the other hand the same people are rigging their houses up with upwards of 1000 incandescent bulbs and even appearing on the news websites with their excessive illuminations saying their power bills go through the roof, but they don't care as it's only once a year for Christmas
A tree and maybe a couple of lights in your front window perhaps is fair enough, but going all out National Lampoon style making each lighting rig bigger than last years (or your neighbours - like it's something to 'prove') is a bit hideous and tacky in my view.
Merry Christmas everyone

Rob
