We have a fenced in (mostly) cement slab on our property. It's meant to be a basketball/volleyball court, but we don't really use it. The plan is to eventually build a barn in that space. So for now it just sits there.
I feed Yard Cat over there, so I pay attention to the space more than anyone else in the family. And we have a ninja snake. It's a snake that climbs the fence (which they do) and then vanishes into thin freaking air. I want to get a picture of it because snakes climbing fences is really neat to watch. But he's never there when I actually have my camera on me and when I do see him and run back to get my camera, he's *gone*. And I can't figure out where he's disappearing to. Snakes are fast, yes, but he's climbing *up* the fence. So I don't know where he's going along the fence. It has vines, but it's not so overgrown that I can't see through them to the fence itself. *frowns*
He's either a ninja or a phantom snake. I'm not sure which.
