I live in the little pocket of "East" Pilsen that used to be heavy in industrial/manufacturing business--the building I live in was the old Burkhart bottling factory. We're also within a stones throw of the highway.
We have a courtyard garden, and lots of edible things could (and do) grow in it, like chives and other herbs, tomatoes. And I won't eat 'em. I'm a little freaked out by the possibility of the soil being contaminated and the "fallout" from the highway, the nearby power plant and other environmental factors.
I know the easy answer is "grow stuff in a box" (landlord doesn't really allow extraneous stuff in the courtyard, nice guy that he is), but I also wonder...am I being paranoid? Would you eat it?
