Nearly every year right after Thanksgiving, mom would put up the Christmas Tree while dad would put up the outside lights. When we were old enough, we were assigned to help mom. It was more than a little task of unfolding groups of branches (we had artificial trees as far back as I can remember):
Fast forward 35 + years (yikes) and I still spend the day(s) after Thanksgiving putting up the Christmas decorations. I usually start with the outside and work my way in. You can see dramatic differences between our tree then and my tree now:
I hope it's a long stretch of time before I can put presents under the tree again!
