There is a field near where I live that is surrounded by a wire fence, as pictured below.
I don’t know if you noticed, but attached to a rope near the top of the fence is what looks to me like a snail hanging by its shell.
I’ve walked past the fence innumerable times, and every time I pass this section of it I’m surprised anew to see the snail. It’s been there for years, the same snail in the same position.
As intrigued as I am to think that a snail could a) hang onto a rope in this manner, and b) remain there for years on end, I’m even more intrigued to find that it isn’t in fact a snail at all.
