The summer I was 18, I worked on a farm in Crestwood, KY. The farm had been idle, and was being brought back into production. Some alfalfa had been planted, hay was being harvested, we put a water line in, several hundred feet, from the road to the house, did some barn painting. But, the biggest portion of my duties that summer was repairing bahrb wahr ( that's "barbed wire" for all y'all not fluent in Kentuckinese). The farmer brought in 25 head of black angus, and I learned two things: first, individually, pound-for-pound, most cattle ain't much smarter than dirt. But, secondly, cattle in a herd have a collective intelligence - what one cow decides to do, pretty much all of 'em decide to do. Sometimes, there is that one smart cow who kinda orchestrates things, deciding what to do. You gotta keep an eye on 'em, particularly that smart cow, because the strangest notions enter into their little heads....
