    The Past For Comparison

    Mike Wallace was nice enough to pull out the sections of Gotham specifically referring to past epidemics and put them all in one place: A Tour of the Plague Years in New York City. Some of it seems familiar, some does not. For those not familiar with Gotham, Wallace and Edwin Burroughs capture New Y…

    Construction History: Summer In The City
