Argyle here. First, fantastic grid spanners and some interesting fill. "Board", in the past, would indicate all meals, not just breakfast. I think you can find B & Bs that do offer meals now.
Unfortunately, many a young couple have bought an old house that they thought would pay for itself by running a bed and breakfast. It's not that easy.
If you ever come to see me, I have a friend with an excellent B & B. Link.
