The "truck comes from everywhere" line got me too, heard almost the same thing from a guy selling "local" corn that still had Florida tags on the crate. What worked for me was just asking straight up where the stuff was picked that week, and watching how they answer. The ones who actually farm it will tell you the name of their place and what is in season right then, and they do not get weird about it. The ones who are just reselling get vague fast or start talking about their supplier network. I also started going earlier, like right at open, because the real growers sell out of the good stuff by 10 and the resellers are the ones still stacked at noon. Ask about next week too, a real farmer knows what they will have, a reseller has no clue. Sticking to one or two stands that pass that test beats wandering the whole market every week.
