How Many Holes?

Can you spot all the holes in this photo?

One of my neighbors has let their dog dig in the back field. Some of the holes are easy to spot, but a lot of them are invisible even when the grass is cut short.

I tripped in one of these invisible holes a couple of months ago and totally wrecked both of my knees. I could barely walk for a few days, and they still hurt.

I’m sure the dog’s owner hasn’t given a second thought to how dangerous those holes are. There are five of them in just that one photo, by the way.
