So if each private section erects a square-shaped pillar which has a side of ~3 feet at each corner, would that be both legal, and sufficient to prevent people from crossing?
No, the judge said, you can cross the corner as long as you don’t step on the private land. The land owner may not create a physical obstacle at that corner. And if there is one, you are allowed to scale it to get to the other side of the corner.
It would be pretty hilarious if the land owner here gets charged in connection with blocking access to public land with the chains.
Similarly, I wonder if there is any room for suits over valuation of land predicated on the exclusive use of inaccessible public land. Someone at some point has definitely advertised this as a plus of owning the adjacent land.
Alternately, a tall fence?
