What showed up outside the window

The neighbors are doing some construction, and we were a bit concerned when a large backhoe showed up right outside the kids' windows - on the only patch of dirt that wasn't being moved as a result of the retaining wall that was being built.  Thankfully, this work looks to be a bit higher quality than in the previous version, which appeared to just be cardboard and a bunch of dirt - which the DeHarts fortunately caught when they were here in the summer.
