We were stuck in a traffic jam for at least 20 minutes with no sign of movement.
There was a field to my left with one horse in.
He/she had it's head down to the grass the next thing it just started to run around the field
it looked like it was having a good time. Then someone got out of the car a few places in front
Horse stopped put it's head down as though it hadn't moved.
I'm not a horse person so don't know if it's normal behaviour.
