I did not know that tomatoes ripen that early in Missouri. Do the tomato plants keep producing until the first frost?
yes. The Mennonites start seedlings in temporary greenhouses. They’re smart business people too, selling their tomatoes for $3.65/lb, until competing fresh tomatoes arrive at the end of June. Then their price comes down and they have lots of other stuff to sell, including hard-neck garlic, onions, beans, etc.
