My dad has started off a trend in his street - he had a santa's sleigh light up thing hung up over his front window last year - this year there are already 7 houses with outdoor lights up and his neighbour has a huge blow up Winnie the Pooh. My kids love it of course and i love seeing their faces. On the other hand though i think it's completely tasteless - every house has different colours and clashes with the next one. And it's totally wrong when you consider global warming. Not much sign of cutting down of carbon footprints in our street.
