Old Concrete Fence Base
While inspecting the yards you will run into all
sorts of things and this is one of them, an old fence post footing of
some sort.
This could have been used for something else but never the less it is a
4 x 4 wood post that has rotted and the footing has been left for the
next home owner to remove.
Usually they are no more than 12 inches in the ground and they are not a
big deal to remove.
It is always a good idea to remove stuff like this from any yards if
possible. They can create problems when some one starts to dig a hole or
even a bigger problem if someone is going to rototill the yard.
