I'm just off out, but here's a thought to ponder while I'm off learning about what it's like to be on a local authority scrutiny committee.
Jim was perusing the HNBOC membership lists earlier and said (amongst other, similar, expostulations) 'Greenlaw? What's Greenlaw?' ... Town Class, I muttered, without looking up from my Christmas wrapping (although to be honest I had thought it was a butty until I checked). 'Town?' he said (hmph hmph). 'Where is it then?' Scotland, I think, I said. 'Didn't think they had Scottish ones' said he. Good point, I thought, we'll look it up in your 1922 Lippincott's Gazetteer of the World.
And there it was, on page 729, Greenlaw, the county town of Berwick, Scotland, 18 miles WSW of Berwick-upon-Tweed. Population (albeit in 1920) about 650.
So the thought I now leave you with is this: was there a boat in the GU fleet named after a smaller town than that?
