STRAIGHT ROWS

I mentioned last week about the proliferation of hazelnut orchards.  Well I forgot to tell you this.  I over heard this guy in a cafe saying that all of these trees are plotted by a guy with a gps.  I couldn't imagine why the placement of these trees would need to be so precise.  I asked a farmer at the golf course.  Some of the farmers already have driverless, computer guided tractors.  Holy cow!
I drove tractors from age seven to about 20.  I loved it.  What is my world coming to?
