This is a travelogue with mediocre literary merit; but, it is so packed with interesting detail, scenes, history, and anecdotes that it makes delightful light reading for Anglophile people like me who cannot travel afar and want to see through the eyes of books. Dartmoor, the Lake District, skylarks, puffins, lochs, it's all in here.
The Christian perspective: An undercurrent that stood out to me was a sense of trying to fill a bucket (think bucket list) with places, scenes, and memories, and somehow trying to convince the reader, and the writer himself, that this was satisfying enough - without God (he mentions with reverence the great work of naturalists like Darwin who opened the door to science without a need to "resort to the supernatural"). We now have the wonderful world of nature and science, we are not deluded by religious baggage...but, how quickly life passes, and we cannot hold onto it... Even as I enjoyed following the journey, I didn't really envy their opportunity, because I could see that even such a long-awaited delight as traveling in the English countryside can not make a soul without Christ really happy. It was a grand checklist, but ultimately for what?..
That was a philosophical musing on an undercurrent. I don't think that undercurrent floods out the whole book, but I thought it was worth reflection. The fact that this was published in 1979 also makes it uniquely interesting. These are people who have been through WW2, in the modern world, but much less than we are. That in itself adds interesting perspective to the whole read.
