Do councils know what we don't?
I think councils know exactly the same as we do that if covid numbers start to get out of hand this autumn, the government won't do anything effective until it's too late.
That could lead to significant numbers of people staying away from big events unilaterally, OR numbers at the events being reduced by covid restrictions to the point that they become uneconomic, OR the events could end up cancelled altogether, possibly a day or two after the Prime Minister insists they won't.
Plus all the Brexit logistical problems. shortages of goods and staff and not being able to rely on things arriving in a timely manner.
In our area things seemed scaled down, and earlier than usual.
