This may or may not be true. I don’t know how the corner crossing issue ever became a law or imposition, but in simple Geometry, I did learn that a point on a plane has no dimension and I am assuming that is the genesis of the issue of not recognizing a corner as a point of access.
How it has turned into such a critical concern is interesting, but I can’t see why it can’t be resolved the same as the stream access bill that allows trespass (if you want to call it that) onto lands that have free flowing water and be able to fish those streams.
Lines have been drawn and there is so much emotion about the rights of access, I can’t help but think a little legislative action could solve the problem to allow access at a corner that now seems to be contested…
