But not a musical reference this time;
The rock is because the landscape is dominated by outcrops of granite bedrock everywhere, which the roads drunkenly weave between, and pine trees somehow cling onto.
Also for the bronze age rock carvings found in this area, from a time when sea levels were 15m higher. Only 3000 years ago!

The roll is for Volvo, meaning "it rolls". The high Volvo density is justified by the fact that the company and factory is based in Gothenburg. Have even seen a VW van with the Volvo badge glued on the front!
Visited the museum which contains a full history of models, from early american style whales, thru stylish 60’s sleek curves to the classic 80's box shapes and the present variations, you can see the common DNA in design throughout.
Volvo cars are now owned by the Chinese....

So in Gothenburg I had a delightfully relaxed stay with Lena and Lasse, thanks to the worldwide influence of Monday Night Football and Axel back in Nottingham.
They are keen ornithologists, with a goshawk in the living room, a clock which strikes the hours by different bird calls, and while Lasse is in the elite club of having observed all 300 of Sweden's native species, Lena has a published book on encounters with those you might find in your garden!
I learn that the swift, when it learns to fly, stays airborne continuously for maybe three years, only eventually coming to earth to rear a family. I can't help thinking there is some easy parallel or metaphor to make there.

I'm afraid to say the rest of the city got the whirlwind photo tour treatment, since I spent most of the time off napping. And what a great nap it was!
