I must resist the temptation to think a longish journey is “too much” if I am to retain my independence and not feel like a feeble old woman
I can fully relate to that MawBroon. Over the years I have driven (alone or with the children) the length and breadth of GB. I cherished my independence. (And still do.)
However, I now let himself do most of the driving. I am rather wary of going on long journeys, mainly because of the volume of traffic everywhere, road works, jams, delays, detours. I seem to hit them all and it's frustrating and yes, very tiring. I try not to drive at night now either, if I can help it.
In July I am staying with a friend who lives about 90 miles away. I am finding myself steeling myself already for a long journey. Once I am on the road I tend to feel better.
So, in answer to your question, I much prefer local driving these days, and I try to ensure I am on the road after the morning rush and home before the rush that seems to start at 2,45pm when the roads fill with 'school traffic'. I have no qualms about driving to and visiting nearby towns, about ten miles away or so, for a change of scenery.
I will do long distances if I have to, but I really don't look forward to them.
