I have very mixed feeling on this, on the one hand I fully understand the feelings of those living in National Parks and their unease at this new advice.
On the other hand I have been fighting my natural urges to jump in the car and head for the hills, especially when things get a bit on top of me, reminding myself that I must be a good chap and wait until the official advice tells me this is OK - and that I have done, thinking how good it will feel to be free to go back to the freedom of the areas I love to visit.
Well now it seems that moment has come - except every man and his dog is saying, directly or indirectly, that I would be foolish/inconsiderate/selfish to take advantage of it. They may well be right and on balance I'll probably leave it a bit longer. However it's a strange shift to be no longer restricted by official policy but now by popular opinion and social pressure...
