It's not "easy" to find mutton in the UK either. My definition of easy (as for the vast majority of the population) is "is it in the supermarket". I don't think I've _ever_ seen mutton in a major UK supermarket. It's somewhat of a catch-22, but the supermarkets don't stock it because there is no demand (modern palates prefer less "gamey" flavours), and there's no demand because it isn't stocked.
