I am amused by this story, about a BBC duo who plan to spend a fortnight travelling across the United States speaking only Spanish.
It reminds me a bit of the Popeth yn Gymraeg challenge of a few years ago, in which Ifor ap Glyn went around these parts using only Welsh. But the Spanish-in-the-USA challenge is considerably easier -- especially when you look at the BBC crew's route. I reckon that one could perform the same task following a route that hugs the U.S.-Canada border; running through places like San Antonio, El Paso, and Nogales will be a cakewalk.
I want the BBC to pay me to do really easy things. Send me to Ireland to discover whether I can find any people who drink Guinness. Lock me in a room with a naked Reese Witherspoon to discover whether I find her attractive.
Spanish speakers can follow their journey via a BBC blog.
