While we were first tempted here by the prospect of a Lego-sized model of the presidential digs, this is in fact the spot where ex-president Harry S Truman used to vacation when he wasn’t molding post-WWII geopolitics. It's lushly luxurious and open only for guided tours, although you are welcome to walk around the surrounding botanical gardens for free. Plenty of Truman’s possessions are scattered about, but the real draw is the guides, who are intensely intelligent, quirky and helpful.
