Move up 50 years; We were removing rocks from a pasture, used most for erosion control.
Had a ten year old driving the Gator. Moved multiple loads of rocks to a pasture corner and built a three sided enclosure.
He asked Why?
Me: Why not build something? We are moving rocks anyway. If we build it cow proof, it will stay for many decades.
If you build it cow proof, they will come.
