I have been aware of adverse possession and it uses since childhood. I lived in Parkchester in the Bronx, owned then by MetLife. It was then the largest apartment complex in the world and the buildings were arranged around private streets, generally cul-de-sacs. Once a year, the management would block entry to these streets (one at a time), until all the cars had vacated, and repaint the parking lines. But, the main objective was to prevent adverse possession by the renters.

I bought my first home in Connecticut in part because it had a 'shortcut' in the back to the local elementary school, and thus my kids would have an easier time going to school. It was in general use by the neighbors' kids as well. I would also block it at least once a year, either by tape (when resurfacing the driveway), or by piling huge mounds of snow across the trail. I just wanted to take no chances. (The driveway, which ran along the property line, also went onto my neighbors' lot at the turning to the garage. I guess I could have claimed adverse possession, but I chose to inform my neighbor and we agreed that it was not a problem.)

The value and equity of the law is debatable, but it is the law, and homeowners should be made aware of it and react according. Note that even if the encroacher does not take possession of the property, he could claim the establishment of an easement by adverse possession, which could limit any attempts to sell the property. We have seen cases like this at our PZC meetings.

And things are getting worse. Australia is trying to move from red to black!

If you look at the TSA page, the larger batteries (>8g) are used for professional video equipment. One corollary aim of this regulation may be to restrict the travel of news crews.
