They have a tree up, in any case. We've never really done the outside lights deal. We did last year just a little...but they're so far off in the woods that only we see them and the kids at home aren't really that enthusiastic about putting 'em up.
My family's the same way. We have a lighted wreath that gets hung on the side of the house each year - it's about six feet high but that's it. Our house is too tall to put lights on, anyway, Dad would kill himself.
