We've just pitched on a CL site near Caernarfon. On the way out of the town a following motorist raced past and braked suddenly in front of us. Then proceeded at 10 mph , then stopped for nearly a minute. I expected him to get out of his car with a wrench in his hand. Other cars behind got a bit inpatient. He then raced off. We had locked all the doors and the dashcam was on. But we did fear for our safety. The first experience of this sort of thing and it has left us shaken up a bit. More than I would have anticipated. I hope this sort of thing does not happen often.
