Basically, the Federal government is only supposed to own the District of Columbia, and various military (and similar)installations. I don't recall the exact language and I'm too lazy to look it up this early on a weekend. I do know that there is ZIP in it about "national parks, national forests" and all the rest of the so-called "federal land". In my opinion, ALL of these lands should be the property of the states in which they are located, and should be turned over to them.
"Federal land" is turning into just another socialist boondoggle.
