According to the article, she lives in Watchet, has jobs in Minehead & Wiliton. The Over Stowey place is (Google maps) 7 miles from Wiliton, 9 miles from Watchet.
So the "she did wrong" scenario is saying she drove 9 miles for a walk (by herself) or 7 miles for walk by self (with pause for food, eaten by herself).
Driving 7 miles to go for a walk is OFFICIALLY ILLEGAL.
Or so it seems, if you think Police did right.
And now you know why I'm afraid to drive 5 miles to the beach.
Tomorrow I'm planning to cycle 9 miles to try to get my covid jab. Does anyone think that's allowed? I mean, I won't wait to get the jab if the Q is more than 1 hour wait. So then I will have gone 9 MILES purely for exercise. and That Is CLEARLY Not Allowed. Is it? I probably shouldn't risk it, should I. I don't care if I never get the jab anyway.
