I think the corner crossing basically said that the owners of corner-corner can't claim the 'airspace' exactly at the corner and there is more or less a de facto low-airspace easement at the corner.

I'm not sure that it created any sort of ground easement.

It basically allows you to 'hop' from one quadrant to the cross quadrant without touching the other two quadrants of the corner. The guy in that case used a ladder to do that IIRC so he only violated their 'airspace' up until that ruling.

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.
