I think part of the problem you're finding is just that nothing is in season in your zip code, maybe? I don't really know Southern Indiana but I wasn't surprised that there were no real local results around me here in SW PA.
Up here in northern New England, I just harvested kale from my garden, and my CSA pickup on Sunday had a nice variety of squash, root crops, greenhouse spinach and cabbage. I'm sure there's plenty of things in season in southern PA.
