Makes me think of one of our local mysteries. A neighbor about a block away has had a big box sitting in their driveway for *years*. It's a large rectangle about the size of a big tall dresser, sitting on a pallet, and completely covered w/ a green tarp. The driveway is also angled, so the box also looks like it's about to tip over any second. We drive by it on the way home, and have come to call it the Green Obelisk. We like to make up crazy theories about what it is, and start chanting/saying "obelisk" ominously when we see it (if you listen to the Welcome to Nightvale podcast, you get it).
We even ran into the neighbor who lives there once and chatted w/ him, but didn't ask about it. The reality about what's under there and why it's been sitting there so long is probably boring.
On an unrelated note, while driving recently, we saw a license plate that read "CALI MA".
