Early aerial photographs of Hudson show that once upon a time the Second Ward looked pretty much the same as the First Ward. The grid pattern of the streets was regular. Houses and buildings stood on 26-foot wide lots with a relationship to the street that is identical to that which still exists in the First Ward. A walking tour guide, written by Ruth Piwonka, to accompany a book signing celebrating the publication of Bruce Hall's book Diamond Street in 1994, suggested that, already in the 19th century, the south side of town was considered marginally more affluent than the north side. It would seem that the economic gap between the neighborhoods on either side of Warren Street--below Third Street at least--had widened by the 1970s, because when the city fathers decided to eliminate what was allegedly the "worst housing stock in the state," they targeted the Second Ward.
