Last year we put some simple maps in the kids stockings that led them to the tree, which we had set up in the woods. We then brought them out to the woods where the maps led us to. We left a trail of ornaments from the road thru the woods that lead to the tree we decorated in the middle of an "enchanted" forest. The few gifts were under that tree. The kids enjoyed it, and we will do it again with more sophistication as they get older (now 5 and 3 years old). One of the objects for us parents was to take the emphasis off of the material things, and make it more about the experience. We struggle with Christmas every year because we aren't exactly into what the whole thing is about, in other words we don't belive in Jesus. Yet the kids are bombarded with hype by the rest of the family, peers, school, television, radio, stores, and the giant Christmas marketing machine in general. I felt geocaching was the perfect way to defocus the whole mess.
