I still don't really understand this. If I own 2/4 grid squares in a checkerboard, can't I go in and put some tall fences on the "corners" of my property. Maybe the two fences are physically joined. But my fences are 16 ft tall, how are you going to put a ladder over that?

It's been awhile since I read the case; I'm not sure that it contemplated that.

If I recall correctly it was either basically just a low hanging chain or low fence, but it's awhile since I read it.

Judges are normally loathe to consider much more than the narrowest reading required, so I would be shocked if they considered the possibility of touching the fence or a fence high enough to make a ladder impractical.
