I had a similar reaction to the discussion of farmer's markets. Technically yes, I've been to markets where it's obvious some vendors are not selling local produce but in the vast majority of the markets around me it's equally obvious that they are (I actually think most of them have rules that the produce has to originate within a certain radius). And selling "5 different types of produce" all grown locally at the same time is hardly difficult to do. Different produce does in fact ripen around the same time.

It made me wonder about the rest of it.
