Just spent a very pleasant 5 days in Ludlow. As we drove round the area we went in and out of Wales. We even had a walk around and a very nice lunch in one small Welsh town. There were no tumbrils being driven round with some one shouting 'Bring out your dead'. In fact the natives looked healthy and were very pleasant. We took all possible precautions, hazmat suits and independent breathing apparatus and when we got back into England, stripped down, burnt everything we were wearing and wiped ourselves over with caustic soda.
Actually we wore masks and I wore gloves, those alcohol based hand sterilisers play merry hell with my skin. We were staying at a friend's house and we trust her and her cleaner. We ate out every day and loaded up with game, cheese and delicious Indian street food from local shops and the market before we travelled home.
We are home safe and well, so far and off to visit DD tomorrow, she is part of our bubble and, like us, lives in a low COVID incidence area.
Just remember you are currently more likely to die of a stroke, heart attack or flu than you are of COVID. Not to mention the dangers of the drive to your holiday destination and driving around while there.
So enjoy a holiday in Britain while the good weather lasts.
I am not cavalier about the risks, I assess them carefully for each situation I am in, but I reckon I am more at risk in my local town centre than away on holiday - and even the risk in my town centre is minimal.
