While the other stump was allowed to be with nature, this one had an added man made object on it. This stump is on the edge of the property between my house and that of a neighbor's. As one can see, a reflector (added by someone unknown) has been placed on the tree.
This reminds me of the Site Seer project that our professor did where he left foreign / man made objects (a white dress, apples in a bowl) in a natural setting and revisited it later to see how it was modified. However, this is the opposite. A natural object was allowed to remain in a man made world and was later modified by man. Again, this is a very permanent piece. Who knows what I will find the next time I return home?
