A great piece in the New York Times today about urban foraging from neighborhood fruit trees, all over the country.  Sadly, other than some Japanese wineberries that grow in an abandoned lot (I checked the other day and they're just about ready to flower), my own neighborhood features mostly inedible ornamentals like Bradford pears.
