Produce under the "local" signs was from as far away as Europe and New Zealand, and even the government's definition of "local" is 400 miles -- from Boston to Cape Hatteras. Great reporting. Exactly the kind of shoe-leather work that bloggers like me aren't going to do because it takes serious time.
The Sun doesn't say that you're being completely manipulated and shouldn't believe the signs. But I'm not a big newspaper that sells ads to the supermarkets. Even when I'm telling you about a truck selling "local" produce, I say "Who knows?" People lie -- or they get the government to define "local" to include Boston.
Thanks to CJB for the tip about the Sun article.
