Today we cleared the rocks out of our backyard. This is part of the preparation for re-grading the soil, installing a sprinkler system, and dropping in sixty (yes, SIXTY) tons of topsoil and compost.

In addition to the fun fist-sized rocks peppering the yard, I came across two enormous chunks of concrete buried just beneath the surface. Each one easily weighed twenty pounds. What in the world are chunks of concrete that big doing in my backyard?!
