These are a fruit of Haiku Poetry Day 2016: a response, during a long train journey, to stimuli received via Twitter.
Firstly, one about QR codes -- those things like crossword puzzles that you see on some notices or packages. My take on them, from the 23things course I pursued in 2011, is at http://bit.ly/nFFqnz . Some maintain that the life of this technology is already limited, but you can follow http://bit.ly/1Vwl7sn for a story about the codes' use on gravestones. My response was:
QR codes to stay
on, enshrined by enshrining,
half a life longer?
And then there was this. http://bit.ly/1NJEZAr takes you to photographs of a royal train arriving at Brecon, in South Wales, in 1955. Brecon Station closed many years ago. One afternoon in 1975 or 1976 (I've checked both diaries; the incident isn't mentioned in either), on a family holiday in Brecon, my parents, my sibs and I mistook the disused railway track, as shown on the map, for a footpath, and followed it. Despite that foundational map-reading error, we made it back to where we were staying.
royal train, Brecon Station;
brambles, barbs, no path.
