Since I'm on a Google StreetView kick today, I'll post this bit of oddness which is very likely an illusion. Keep in mind the StreetView photos of the house are from October 2016 so are two years old.

Note what appears to me to be a stack of picnic coolers, perhaps? The red things. Who needs that many? Maybe they're something else but they're not what I'm looking at. Doesn't that rather look like a person? Note the same set of StreetView images show no cars in the driveway. Here's my probable optical illusion outlined:

One could wonder if there was a long-time stalker. It's likely leaves near the Google camera that just make a nice illusion. But I am curious about the stack of coolers(?).
