Does anyone have experience with farming in light industrial zoning?   
I imagine the rules vary from town to town, but any general experience  
or insights?  My thoughts are, of course, buy cheap unused industrial  
property and start a farm in the city.  Specific concerns are zoning  
restrictions and contaminants in the ground (would raised beds help in  
any significant way?).  I've heard of gardens going up on top of  
asphalt in Detroit, so it seems to me that contamination/hardpan may  
be possible to overcome.  Furthermore, would the siting affect the  
health departments allowing of produce to be sold?

Thanks for any input.
