Let 'em light, let 'em last.
I'm all for holiday lights lasting waaaay past the holidays, at least well into January. And, heck, why not into February, too? We all start to feel to so glum around that time. It gets dark so early, it can be bitter cold, it's a bleak time of year. Why not have something a little festive that lasts long after the Winter Solstice before the next happy holiday hits (Valentine's Day, which, granted, for some can bring more pain than pleasure).
