@sionned, diolch yn FAWR for keeping the map going through the many travails of the early days up to the glorious present. Am I misremembering, or didn't Google Maps wipe us out entirely at one point when Google was changing its technology....?!
There's actually a book in which a Welsh learner did that: Pamela Petro, Travels in an Old Tongue. I don't always like her take on the Welsh expat and Welsh learner communities she encounters, but the book is great fun for Our Kind to read.
