Sheffield has gone from one of the highest in the country a few months ago to pretty low now - for a big urban centre at least. So the recent restrictions have worked here for sure. They're slightly going back up, but not by much. I don't feel we're being 'rewarded' by being kept in Tier 3, but clearly where folks are making a demonstrable effort, all other things considered, then the measures shouldn't be too draconian as it's unfair and counter-productive. Clearly something is different considering the numbers elsewhere. Maybe our excess of woodland means more people are meeting outdoors? I've never seen so many people out walking, even in winter, which is great really, as long as everyone doesn't bunch up.
I find it hilarious and sad in equal measure that folks would drive to a lower tier area for some 'non-essential shopping'. The clue's in the name.
