This was another mystery for me while walking on seemingly abandoned cemeteries in Scotland: why is the grass seemingly cut? Many of the cemeteries were not even. There were usually no buildings other than the abandoned chapels. It didn’t look like someone had used an electric power-driven lawn mower (how can one have done this without a power supply) or tracks of a fuel-driven lawn mower. On the other hand, the uneven ground would have made it extremely hard to use such a device. But, you can definitely see, the grass is very short.
Maybe we can see the reason in the back of this image: sheep! they are running around everywhere freely and you have to drive carefully because they don’t obey human rules on how to behave correctly in the streets and they don’t interact with the car drivers.
