The week of Thanksgiving 2008 is National Family Week, a chance for families of all stripes to get closer and become stronger. There are lots of good links out there about the week-long celebration of family ties, genetic and otherwise.
National Family Week was first made a reality in the United States in 1987 under Ronald Reagan.
Here are a few links that may help make your celebration more fun:
