Lovely humble stop! Nearby there is a splendid upscale station, infinitely long with infinitely many evenly spaced metal benches and bins, serviced by an infinitely long train, where the Manager can always fit yet another bus full of travellers. QR calls it Townsville; I call it Hilbert's #mathsky

The pedestrains have been crossing here for at least the last 10 years, but no gunzel has ever snapped one with their SLR

Disgraceful. They are probably serving lion steaks, too

Yes! Like my new, teeny-tiny, hardcover bound notebook with cutaway alphabet index! Isn't it scrumptious! What a find!

These helpful signs have popped up in Canberra parks, thus showing the prisoners where to forage

Had a terrific Friday evening walk & shop! Bought a beautiful spotted shirt at Vinnies! Took it home, tried it on.

Erm... sometimes, there is a good reason why someone sends a clo to the charity shop bin. Oh well. It was fun browsing the bric-a-brac anyway.

Yet, sometimes one's terrible mobile phone pictures of the moon can yield unexpected beauty

On the day the book is published I'll send you a smoke telegram. You will have to unroll and decode it, relay it on with perfect fidelity, and send back an acknowledgement.

The boutique gin turned out to be a good fuel for a tiny steam engine, so all's well that ends well

You mean CALONC.
The name had been changed to Galong by 2018 tho

Interesting. There scope for such ideas to broaden too. That manuscript was handwritten by Hilbert's wife Kathe. It actually says: 'Mathematics knows no races. If we look at the history of our science, we see all nations and peoples taking successful and equal part in it...

Cautionary sign of the day. Geology forbidden. Fair enough. What's the penalty tho?

Roadside sign of the week. Not a sign you see every day.

Not an animal you see every day either. (I didn't.)

Meanwhile, in Tasmania.

Furious farmers drive fifty tractors through the streets of Deloraine to protest a raw potato deal from cheap imports. Beaut little Fergie tractors, too!

Oi, all you chip-addicts, pay a fair price for your fix and support Tassie 🥔 growers!

Oh does it now? This machine at the laundromat washes and outputs your clothes all folded? Well. I shall give it the dreaded fitted sheet test!

Aww... there is hope, O ye ANU colleagues

'The global fashion industry could soon produce enough unworn clothes to almost stretch from Earth to Mars and back'

That's going well then. We Aussies started that project in 1975 from the tail of a Qantas B747, only it was unwashed rather than unworn in that great era.

Mount Gambier station two weeks ago. Such gables! The building is untenanted and in poor shape tho. The precinct was dumped on the local council, which is clueless wrt rail heritage. No-one wants to pay for it. What is to be done? A cafe/gift shop/art gallery? Sure, until it goes broke.

Meanwhile, 4000 km north in the Gulf country they are not troubled by gradients. The game of playing mixed goods trains with vintage engines and wagons on a real railway is still heaps fun tho! #trains #railways

Saturday is also fun day! It is diesel's turn to pull the Mixed Goods. Diesel cannot use the rack of course. Can it make the climb anyway, despite the rainforest ick that is ground into the rail surface? #trains #railways

Even more fun was had uncoupling and rearranging the wagons at the top of the rack section! But the Abt engine cannot be turned there. #trains #railways

Friday is fun day on the West Coast Wilderness railway. The crew made up a goods train with a flat and a wagon and a real brake van then steamed it up and down the rack. They played trains all day long. We hates them and it's not fair. #trains #railways
