I saw them

Not in Canada, but when I was in Portmeirion, Wales on holiday. They were riding around in a buggy filming what seemed like a tour of Portmeirion, I'm sure I ended up in the background a couple of times too. I don't usually give the modern History channel shows a chance seen as how they don't have much to do with history any more, but I'll be looking out for this and it'd be great help if someone could tell me when it airs in Britain.
