1) There was a video demonstrating the use of an atlatl, a spear-throwing weapon that the native peoples used for hunting (and fighting?). I'd read about it before, but seeing it used really helped my understanding of the thing, esp in how far a spear could be thrown: impressive.
2) Early European settlers tried to farm the flint hills, but failed due to the rock just below the surface of the rich soil. Later European settlers started utilizing the land as the Native Americans did, which was to burn the grass every year in order to promote the growth of fresh new grass and graze cattle on it, essentially becoming "grass farmers".
3) The world champion livestock auctioneer (for 2014?) says his "secret" is to treat it like singing.
