Not sure if I'll get this story exactly correct but there's a beachside park in Lauderdale called Birch State Park. The property was willed to the state to be maintained as a public park, otherwise it would revert back to another beneficiary of the original will, some university.
At one point the university greedily attempted a land grab, claiming the park was no longer utilized for the public, which was bullshit. I lived there and enjoyed that property for decades, including during the time of that lawsuit. It had not only always been maintained as an excellent public use of property as intended by the original private owner, but it was always one of our very best parks.
I'm no history buff so I've no idea but that sort of thing makes me wonder if when states were carved within this nation, if those properties hadn't been turned over to the state governments in some sort of trust. And if that trust was violated, then couldn't the country just take back our property?
I don't know but I would think there must have been some conditions. I can't believe the US government gave a state all that property so the state could then turn around and sell it off to an enemy, for instance.
So I wonder what some of those conditions of trust placed on those lands might have been and could they now be enacted. I'd think purposely, knowingly violating the constitution of the country would violate that trust. We should take back at least the Great Smoky Mountains. They're beautiful this time of year.
