We used to "do" Halloween to "the nines" when my children and grandchildren were small, but not so much anymore. We get all the goodies to hand out, but there's very little in the way of decorating. A jack-lantern here and there but that's about the extent of it.
The same for Thanksgiving. Sometimes I'll have a bunch of small fall gourds in a big wooden bowl, and there's usually a small outdoor wreath, and uncut pumpkins outside on the porch, and in the front entryway of the house two fall floral arrangements. That's pretty much it.
Since our kids married and started their own families (families who are now grown up - the grandbabies are all between 18 and 20!) the only holiday I really take time to decorate for is Christmas. For most of the other holidays our small family is somewhat split up and it's rare for all of them to be here for Thanksgiving.
That happens to be the big racing weekend in our area (usually in Peterborough - "Fall Colours") to end the official race season and sometimes one or both of our kids families are at the races, leaving us to do our own thing.
