The brass section

I do, on occasion – and to the great distress of anyone within earshot – quite literally blow my own trumpet. Or, to be precise, these days, a flugelhorn. It began in the early Pleistocene when I was in high...

Returned from outback of beyond

I'm back from the outback - and what a trip! The photo above is entirely undoctored: it really is "The Red Centre." Unfortunately, a key vehicle suffered a catastrophic transmission failure, but fortunately well into the trip and in a...

An Antipodean adventure and an extended hiatus

From this Friday, I will be essentially – and, I must admit, largely blissfully – out of touch with the world. I am off on an epic four-wheel-drive tour of a large chunk of the Australian outback, starting and ending...

Sunday sand: Ngobaran

Sand from perhaps the smallest “beach” that I have visited and sampled. One of the items on the varied agenda of a recent long weekend in Central Java (varied in the way that part of the world uniquely and fascinatingly...
