We went out in the van today and parked up in the country and the whole family went for a walk together (10min drive, 1 hour walk), it’s been really hard to get the kids out of their rooms and especially both together so although I don’t really agree with the need for the new allowance to drive somewhere to exercise it was really good!
I'm glad you enjoyed your walk, the benefits of exercise, particularly in the countryside are known but often underestimated. Vitamin D, made by the skin when exposed to sunlight helps our immune systems. More than ever we need healthy minds and bodies.
The "risk" that you took was next to non existent and was far outweighed by the benefits to your whole family. As long as we use common sense (short drive long walk, don't touch gates unless gloved, stay well away from others etc) it's not a problem.
The law hasn't changed, (it was rushed, vague and badly worded) just people's interpretation of it.
