outside of my window at work there's a construction site. every day there are people there. as best i can tell all they've done is move dirt around from pile to pile. the lady who sits next to me said they've been doing that on and off for 2 years now (the project had some funding and approval issues). what are they actually doing? all i see is take dirt from pile A, move it to pile B, then a few weeks later move it back to pile A.
