There is an old people's home which I'd known about for some time, and recently confirmed its continued existence during my trip to Cornwall. I should have taken a photo of the sign as it highlights the perils of naming your house using a language, with which you are not fluent.
I greatly suspect that when they chose the name Chy Byghan, that it was done by using one of those "name your house in Cornish" type books. In Welsh, it would have been Ty Bach (and by now the Welsh speakers amoung you will see where this is going....) Literally, a small house (which is all very nice) but in normal usage that refers to a toilet which is perhaps not the most tactful name for an old peoples' home!
After a good number of hours of continued editing, I've now just about caught up with the backlog of tracks and data which I'd gathered in the last week. The main conclusion from all that work is that there is still a lot to do in Cornwall, even (or perhaps especially) in the main towns and cities. If I get a chance to go back at some stage, then I'll certainly be taking my GPS and adding to the map.
