Sorry this is a bit tightly framed, but I was using a long lens and I couldn't get far enough away when I spotted what they were doing.
Okay, so out in Anglesey walking up the mountain/hill. Near the top we came to a dry stone wall. In the gap between the ends of the wall was a large wooden gate, then a short length of fencing and then another gateway. A quick look at the right of this shot will show the empty hinges and the fact that the next gate was missing. Not sure why it was necessary to have two gateways but I just walked through the wide gap.
Looking behind me I saw that the monsters had decided to take the easy way past the wall.
