No such thing as land that is not owned

In Germany there is no such thing as land that is not owned. All property is spoken for by someone. This made me think if the same can be said for the US. Is there any property there that no one owns? Initially I thought no there cannot be. But, now I think that maybe in some parts of the country there might be land that no one claims.

This point came up in a discussion with a German friend about fishing and hunting. In order to fish and hunt here you have to join an official club, take a class which could last six months or so, and pay a yearly license fee. There is someone in the hunting club that owns the land on which you can hunt; I don't know yet if the same can be said for fishing clubs and rivers where you can fish.

Whatever you catch or kill though has to be paid for. You take your deer, for instance, back to the hunting club where you pay the landowner a fee to take your quarry home. The same goes with fish. You have to make an additional payment for all the fish that you catch.

I couldn't believe this at first. I thought it so ridiculous to have to pay for what you have caught. It was explained to me that this is partially an old legacy of the prohibition against poaching, which was a very contentious issue for centuries. It also exemplifies the social hierarchy that pervades all German relationships which although not as rigid as in the past is still ever present.
